Do you communicate data? Do you want to create more effective data visualizations? Tableau is the data analytics tool you¡¯re looking for. Here are the top three reasons why you should learn how to use Tableau, the popular data viz software focused on business intelligence. Read on for the advantages of being a Tableau professional.
#1 Tableau Is Easy
Data can be complicated. Tableau makes it easy. Tableau is a data visualization tool that takes data and presents it in a user-friendly format of charts and graphs. And here¡¯s the rub: There is no code writing required. You¡¯ll easily master the end-to-end cycle of data analytics.
Need to showcase trends or surface findings? Tableau will make you an expert. Proficiency in business intelligence is a transferable skill that is quickly becoming the lifeblood of organizations.
¡°I see students who are new to analytics learn Tableau desktop and be able to develop Tableau worksheets, interactive dashboards, and story points in a couple of weeks ¡ª essentially a complete data analysis project,¡± says Candace Pereira-Roberts, FinServ data engineer and one of our Data Analytics course instructors. She adds, ¡°I like to share knowledge and watch people grow. I learn from my students as well.¡±?
#2 Tableau Is Tremendously Useful
Would you rather tell visual stories with data? Or present the same old boring reports and tables? Is that even a question?
¡°Anyone who works in data should learn tools that help tell data stories with quality visual analytics.¡± Full stop.
The smart data analyst, data scientist, and data engineer were quick to adopt and use Tableau tool by tool, and it has given those roles a key competitive advantage in the recent data-related hiring frenzy. But their secret is out. And the advantages go beyond the usual tech roles. Having a working knowledge of data, and specifically knowing how to use Tableau, can help many more tech professionals become more attractive to recruiters and hiring managers.
Plus, it has a built-in career boost. Tableau¡¯s visualizations are so elegant, you¡¯ll be confident presenting the business intelligence and actionable insights to key stakeholders. Improving your presentation skills is par for the course.
#3 Tableau Data Analysts Are in Demand
As more and more businesses discover the value of data, the demand for analysts is growing. One advantage of Tableau is that it is so visually pleasing and easy for busy executives ¡ª and even the tech-averse ¡ª to use and understand. Tableau presents complicated and sophisticated data in a simple visualization format. In other words, CEOs love it.
Think of Tableau as your secret weapon. Once you learn it, you can easily surface critical information to stakeholders in a visually compelling format. That will make you a rockstar in any organization.
¡°Tableau helps organizations leverage business intelligence to become more data-driven in their decision-making process.¡± Pereira-Roberts says. She recommends participating in Makeover Monday to take your skills to an even higher level.?
Data is big, and it¡¯s getting bigger. How do you parse and understand data when the sheer amount of information can be overwhelming? The answer is data visualization. Using concepts of design theory like elements of color and layout, the discipline of data visualization, or data viz, is essentially the graphic representation of data. We called on one of our data viz experts, Iun Chen, to break it down further.
Let¡¯s start with an introduction and how you came to the world of data viz.
IC: I’m Iun (pronounced ‘yoon’), and I work in the data analytics space focusing on business intelligence tools and building scalable resources for LinkedIn. I also teach the 10-week Intro to Data Analytics course for GA, which includes the professional skills of SQL, Tableau, and Excel.
In college, I was a business major with a specialization in marketing and advertising. I became more interested in how the ad business model worked behind the scenes and in how software and systems worked. As a result, I worked at many major media companies in a quantitative capacity ¡ª revenue planning, ad pricing, finance, ad sales strategy. That led me into a formalized analytics route.
How do you define data visualization?
IC: Data visualization is the idea of communicating information graphically. It¡¯s the science of information design, in which you take massive amounts of data in whatever format it comes in and use it to surface high-level insights and findings in a visually compelling way so audiences can easily understand the main points.
How does data visualization differ from data analytics?
IC: Data analytics is the process of cleaning, prepping, analyzing, and presenting data. Data visualization is part of the presenting data step and is defined as the act of visually organizing data through the use of charts, graphs, and dashboards. Concepts of data visualization are closely aligned with concepts of design theory: color, font, scale, layout, organization.
Why is data viz important?
IC: Data visualization is easy to learn but hard to master. In my classes, I heavily emphasize the design element of data visualization. It¡¯s easy to whip together a quick bar or pie chart, but is it the best way to communicate the point you are trying to make? The goal of collecting mass amounts of data is to be able to quickly translate it into insights that can help make smart business decisions. The final form of this translation is often a chart or graph, which is why the ability to design and visualize these mass amounts of data grows as we collect more of it.
What is a data narrative?
IC: People think in stories and narratives, not in black and white figures. Just like you would share a story with a friend using a beginning, middle, and endpoint, you would do the same when sharing details about data analysis. Here¡¯s a simple example.
Beginning: Sales are down year-over-year; identify the symptoms.
Middle: Furniture sales ¡ª our largest segment ¡ª are doing poorly in the last six months; conduct the analysis to investigate reasons and uncover root causes.
End: Review retail store reports and conduct manufacturer visits; recommend next steps.
The key point to any data narrative is that it should present a compelling business case and surface unrealized insights to the audience. The business challenges, rationale, and next steps should be clearly presented, and people in the room should be able to walk away and know what to action on.
Which tech roles use data visualization?
Data visualization ¡ª like data analytics ¡ª is a skill set that can be applied to any job. But if you are looking for a job that has data visualization skills as part of the function and responsibilities, look for roles like business analyst, data analyst, business intelligence analyst, data scientist, and data engineer. Keep in mind that the formal skill of data visualization is still relatively new, so depending on the maturity of the company, those functions may not be fully established yet. However, with the increase of data in the world, there¡¯s a growing need for experts who understand data visualization techniques more and more.???????????

What¡¯s the future of data visualization?
As we continue to collect more and more data, the need for people with the skills to analyze and present data becomes ever-growing and critical in the workplace environment. More companies will need to generate insights quickly to keep up with advances and competition in their respective industries. The skill of data visualization will become more and more attractive as teams and organizations seek to translate their data into insights more efficiently and effectively. The ability to work with data is increasingly critical to the success of any company in any job function.?
Tableau and Power BI are powerful tools for business intelligence, with capabilities to take loads of big data and create elegant visualizations that convey key insights to stakeholders in easily digestible presentations. Both help organizations leverage business intelligence to become more data-driven in their decision-making process. So which tool is better? We asked a few industry experts their thoughts on the data analysis tools Tableau and Power BI. Here¡¯s what they had to say.
Candace Pereira-Roberts, Data Engineer & GA Data Analytics Instructor
“Anyone who works in data should learn tools that help tell data stories with quality visualizations. Tableau is a wonderful tool for the technical and nontechnical to build these visualizations. I love how we teach the Tableau unit in the Data Analytics bootcamp. I see students who are new to analytics learn Tableau desktop and be able to develop Tableau worksheets, dashboards, and story points in a couple of weeks to do a complete analysis project.”
Iun Chen, GA Instructor & Data Analyst at LinkedIn?
“In my professional capacity, I lead data visualization workshops to share best practices on charting and design theory, with a focus on Tableau. But with the growth of big data analytics, there are more players in the data viz space. Looker. Qlik, Domo, and Microstrategy are a few with out-of-the-box solutions. Check out other marketplace BI and analytics leaders and their reviews at Gartner.
Alternatively, if you are up for the challenge you can start from scratch and build out completely customized solutions through coding packages, such as with Python plotting libraries Matplotlib, Pandas, and Seaborn.”
Matt Brems, GA Instructor & Data Consultant at BetaVector
“Most data analyst roles will expect some experience with data visualization. They may prefer your visualization experience be tied to a certain tool like Tableau or Power BI or simply want you to have experience designing graphics or dashboards. As with any platform, the human element is key. A good data analyst is curious and detail-oriented. Diving into the data and spotting anomalies or identifying patterns requires curiosity. Looking at large datasets for long periods of time can invite mistakes, so being detail-oriented ensures you¡¯re interpreting the data correctly.”
Vish Srivastava, GA Instructor & Product Leader at Evidation Health
?¡°Most teams I’ve seen are not comparing Tableau and Power BI. Instead, it’s more about whether to adopt a business intelligence tool at all, or whether to use Tableau or Power BI in place of Excel. Tableau is a great option when you need to quickly create data visualizations.Tableau is incredibly powerful because it¡¯s designed for nontechnical users, meaning business users can set up and tweak dashboards and charts without the support of engineering or data science teams.¡±
When it comes to research, the most common data analytics tool is SQL ¡ª no surprise there. But once you get into more niche industries, that can vary, says Brems.
¡°In academia, R is probably the most prevalent data analysis tool, though Python is quickly gaining popularity. SAS and Stata are often used in specific industries, though their popularity is diminishing. (R and Python are open source tools, which means, among other things, that they are free.)¡±
We live in a world of data ¡ª swimming in statistics, numbers, information ¡ª and the amount of data seems to be growing faster than we can keep up. More people are using data points to make decisions large and small. From which restaurant has the highest Yelp rating to which city has the lowest rates of COVID-19, using data to navigate everyday life is now the norm. Indeed, the pandemic has only increased our reliance on data. We have come to expect this tsunami of data to explain, and in some cases solve, many of the most vexing problems faced by society today. But finding key insights takes careful analysis of a staggering amount of data. No small feat.
It¡¯s true that more data is released than ever before. In the U.S., there are currently over 290,000 datasets on data.gov alone. Clearly, there¡¯s a growing need for data analysts and the data analytics tools that help us understand these numbers. From small businesses to the highest levels of governments, decisions turn on interpretations of data. Big data can have big consequences.
So how do data analysts find the insights lurking in a database? And what are the best tools to analyze all those numbers? Read on to discover the best data analytics tools in the market.
Data scientist and GA instructor since 2016, Matt Brems currently runs a data science consultancy called BetaVector. We asked him to share his go-to data analysis tools. ¡°People who want to analyze data use many different tools; I like to break these down into three different types,¡± he says.
Let¡¯s get to it.
Type #1: Tabular Data Tools
Data analysts need to get data out of databases and analyze that information. And to do that, they use tabular data tools. According to Brems, the most important ones to know are Microsoft Excel, Google Sheets, and SQL, or Structured Query Language. 足球竞彩网ly considered the best data analysis tool for research, SQL is the most common qualification found in job descriptions for a data analyst.
¡°Most data that data analysts analyze comes in the form of a table, called tabular data. This just means that data is organized into rows and columns, like a spreadsheet. Most data analysts will use a spreadsheet tool like Microsoft Excel or Google Sheets. When working with significant amounts of data (large tables, many tables, or both), organizations will often use a database. In order to interact with most databases, SQL is by far the language of choice.¡±
Type #2: Programming Language Tools
Proficiency in a few programming tools, while not a prerequisite for basic data analysis, can give analysts the ability to perform a wide variety of tasks. While the needed programming language tools will vary from company to company and even from job to job, having this skill set as a data analyst is clearly an advantage for job seekers.
¡°Python and R are the most common programming language tools in data analysis, though Stata and SAS are also used in some industries. These tools can be used to perform automation, statistical modeling, forecasting, and visualization.¡±
Type #3: Data Visualization Tools
Since data analysts are frequently tasked with presenting results to stakeholders, a good data visualization tool is essential. Brems recommends Tableau and Microsoft PowerBI.
¡°While you can visualize data using programming languages, Tableau and PowerBI are two standalone tools that are used almost exclusively for the purposes of building static data visualizations and dashboards.¡±
A Note on Research
When it comes to research, the most common data analytics tool is SQL ¡ª no surprise there. But once you get into more niche industries, that can vary, says Brems.
¡°In academia, R is probably the most prevalent data analysis tool, though Python is quickly gaining popularity. SAS and Stata are often used in specific industries, though their popularity is diminishing. (R and Python are open source tools, which means, among other things, that they are free.)¡±
Python is a popular programming language used by both developers and data scientists. But what makes it so popular and why are so many data scientists choosing Python over other programming languages? In this article, we’ll explore the advantages of Python programming and why it’s useful for data science.
What is Python?
No, we’re not talking about the giant, tropical snake. Python is a general-purpose, high-level programming language. It supports object oriented, structured, and functional programming paradigms.
Python was created in the late 1980s by the Dutch programmer Guido van Rossum who wanted a project to fill his time over the holiday break. His goal was to create a programming language that was a descendant of the ABC programming language but would appeal to Unix/C hackers. Van Rossum writes that he chose the name Python for this language, “being in a slightly irreverent mood (and a big fan of Monty Python’s Flying Circus).”
Python went through many updates and iterations and by the year 2008, Python 3.0 was released. This was designed to fix many of the design flaws in the language, with an emphasis on removing redundant features. While this update had some growing pains as it was not backwards compatible, the new updates made way for Python as we know it today. It continues to be well-maintained and supported as a popular, open source programming language.
In ¡°The Zen of Python,¡± developer Tim Peters summarizes van Rossum¡¯s guiding principles for writing code in Python:
Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. Readability counts. Special cases aren’t special enough to break the rules. Although practicality beats purity. Errors should never pass silently. Unless explicitly silenced. In the face of ambiguity, refuse the temptation to guess. There should be one– and preferably only one –obvious way to do it. Although that way may not be obvious at first unless you’re Dutch. Now is better than never. Although never is often better than *right* now. If the implementation is hard to explain, it’s a bad idea. If the implementation is easy to explain, it may be a good idea. Namespaces are one honking great idea — let’s do more of those!
These principles touch on some of the advantages of Python in data science. Python is designed to be readable, simple, explicit, and explainable. Even the first principle states that Python code should be beautiful. In general, Python is a great programming language for many tasks and is becoming increasingly popular for developers. But now you may be wondering, why learn Python for data science?
Why Python for Data Science?
The first of many benefits of Python in data science is its simplicity. While some data scientists come from a computer science background or know other programming languages, many come from backgrounds in statistics, mathematics, or other technical fields and may not have as much coding experience when they enter the field of data science. Python syntax is easy to follow and write, which makes it a simple programming language to get started with and learn quickly.
In addition, there are plenty of free resources available online to learn Python and get help if you get stuck. Python is an open source language, meaning the language is open to the public and freely available. This is beneficial for data scientists looking to learn a new language because there is no up-front cost to start learning Python. This also means that there are a lot of data scientists already using Python, so there is a strong community of both developers and data scientists who use and love Python.
The Python community is large, thriving, and welcoming. Python is the fourth most popular language among all developers based on a 2020 Stack Overflow survey of nearly 65,000 developers. Python is especially popular among data scientists. According to SlashData, there are 8.2 million active Python users with ¡°a whopping 69% of machine learning developers and data scientists now us[ing] Python (compared to 24% of them using R).¡±4 A large community brings a wealth of available resources to Python users. Not only are there numerous books and tutorials available, there are also conferences such as PyCon where Python users across the world can come together to share knowledge and connect. Python has created a supportive and welcoming community of data scientists willing to share new ideas and help one another.
If the sheer number of people using Python doesn¡¯t convince you of the importance of Python for data science, maybe the libraries available to make your data science coding easier will. A library in Python is a collection of modules with pre-built code to help with common tasks. They essentially allow us to benefit from and build on top of the work of others. In other languages, some data science tasks would be cumbersome and time consuming to code from scratch. There are countless libraries like NumPy, Pandas, and Matplotlib available in Python to make data cleaning, data analysis, data visualization, and machine learning tasks easier. Some of the most popular libraries include:
NumPy: NumPy is a Python library that provides support for many mathematical tasks on large, multidimensional arrays and matrices.
Pandas: The Pandas library is one of the most popular and easy-to-use libraries available. It allows for easy manipulation of tabular data for data cleaning and data analysis.
Matplotlib: This library provides simple ways to create static or interactive boxplots, scatterplots, line graphs, and bar charts. It’s useful for simplifying your data visualization tasks.
Seaborn: Seaborn is another data visualization library built on top of Matplotlib that allows for visually appealing statistical graphs. It allows you to easily visualize beautiful confidence intervals, distributions, and other graphs.
Statsmodels: This statistical modeling library builds all of your statistical models and statistical tests including linear regression, generalized linear models, and time series analysis models.
Scipy: Scipy is a library used for scientific computing that helps with linear algebra, optimization, and statistical tasks.
Requests: This is a useful library for scraping data from websites. It provides a user-friendly and responsive way to configure HTTP requests.
In addition to all of the general data manipulation libraries available in Python, a major advantage of Python in data science is the availability of powerful machine learning libraries. These machine learning libraries make data scientists¡¯ lives easier by providing robust, open source libraries for any machine learning algorithm desired. These libraries offer simplicity without sacrificing performance. You can easily build a powerful and accurate neural network using these frameworks. Some of the most popular machine learning and deep learning libraries in Python include:
Scikit-learn: This popular machine learning library is a one-stop-shop for all of your machine learning needs with support for both supervised and unsupervised tasks. Some of the machine learning algorithms available are logistic regression, k-nearest neighbors, support vector machine, random forest, gradient boosting, k-means, DBSCAN, and principal component analysis.
Tensorflow: Tensorflow is a high-level library for building neural networks. Since it was mostly written in C++, this library provides us with the simplicity of Python without sacrificing power and performance. However, working with raw Tensorflow is not suited for beginners.
Keras: Keras is a popular high-level API that acts as an interface for the Tensorflow library. It’s a tool for building neural networks using a Tensorflow backend that’s extremely user friendly and easy to get started with.
Pytorch: Pytorch is another framework for deep learning created by Facebook¡¯s AI research group. It provides more flexibility and speed than Keras, but since it has a low-level API, it is more complex and may be a little bit less beginner friendly than Keras.
What Other Programming Languages are Used for Data Science?
Python is the most popular programming language for data science. If you’re looking for a new job as a data scientist, you’ll find that Python is also required in most job postings for data science roles. Jeff Hale, a 足球竞彩网 Assembly data science instructor, scraped job postings from popular job posting sites to see what was required for jobs with the title of ¡°Data Scientist.¡± Hale found that Python appears in nearly 75% of all job postings. Python libraries including Tensorflow, Scikit-learn, Pandas, Keras, Pytorch, and Numpy also appear in many data science job postings.
R, another popular programming language for data science, appeared in roughly 55% of the job postings. While R is a useful tool for data science and has many benefits including data cleaning, data visualization, and statistical analysis, Python continues to become more popular and preferred among data scientists for a majority of tasks. In fact, the average percentage of job postings requiring R dropped by about 7% between 2018 and 2019, while Python increased in the percentage of job postings requiring the language. This isn’t to say that learning R is a waste of time; data scientists that know both of these languages can benefit from the strengths of both languages for different purposes. However, since Python is becoming increasingly popular, there’s a high chance that your team uses Python, and it’s important to use the language that your team is comfortable with and prefers.
What is the Future of Python for Data Science?
As Python continues to grow in popularity and as the number of data scientists continues to increase, the use of Python for data science will inevitably continue to grow. As we advance machine learning, deep learning, and other data science tasks, we’ll likely see these advancements available for our use as libraries in Python. Python has been well-maintained and continuously growing in popularity for years, and many of the top companies use Python today. With its continued popularity and growing support, Python will be used in the industry for years to come.
Whether you’ve been a data scientist for years or you are just beginning your data science journey, you can benefit from learning Python for data science. The simplicity, readability, support, community, and popularity of the language ¡ª as well as the libraries available for data cleaning, visualization, and machine learning ¡ª all set Python apart from other programming languages. If you aren¡¯t already using Python for your work, give it a try and see how it can simplify your data science workflow.
At first glance, data science seems to be just another business buzzword ¡ª something abstract and ill-defined. While data can, in fact, be both of these things, it¡¯s anything but a buzzword. Data science and its applications have been steadily changing the way we do business and live our day-to-day lives ¡ª and considering that 90% of all of the world¡¯s data has been created in the past few years, there¡¯s a lot of growth ahead of this exciting field.
While traditional statistics and data analysis have always focused on using data to explain and predict, data science takes this further. It uses data to learn ¡ª constructing algorithms and programs that collect from various sources and apply hybrids of mathematical and computer science methods to derive deeper actionable insights. Whereas traditional analysis uses structured data sets, data science dares to ask further questions, looking at unstructured ¡°big data¡± derived from millions of sources and nontraditional mediums such as text, video, and images. This allows companies to make better decisions based on its customer data.
So how is this all manifesting in the market? Here, we look at three real-world examples of how data science drives business innovation across various industries and solves complex problems.
In today¡¯s digital age, we¡¯re constantly bombarded with information about new apps, transformative technologies, and the latest and greatest artificial intelligence system. While these technologies may serve very different purposes in our life, all of them share one thing in common: They rely on data. More specifically, they all use databases to capture, store, retrieve, and aggregate data. This begs the question: How do we actually interact with databases to accomplish all of this? The answer: We use Structured Query Language, or SQL (pronounced ¡°sequel¡± or ¡°ess-que-el¡±).
Put simply, SQL is the language of data ¡ª it¡¯s a programming language that enables us to efficiently create, alter, request, and aggregate data from those mysterious things called databases. It gives us the ability to make connections between different pieces of information, even when we¡¯re dealing with huge data sets. Modern applications are able to use SQL to deliver really valuable pieces of information that would otherwise be difficult for humans to keep track of independently. In fact, pretty much every app that stores any sort of information uses a database. This ubiquity means that developers use SQL to log, record, alter, and present data within the application, while analysts use SQL to interrogate that same data set in order to find deeper insights.
Finding SQL in Everyday Life
Think about the last time you looked up the name of a movie on IMDB. I¡¯ll bet you quickly noticed an actress on the cast list and thought something like, ¡°I didn¡¯t realize she was in that,¡± then clicked a link to read her bio. As you were navigating through that app, SQL was responsible for returning the information you ¡°requested¡± each time you clicked a link. This sort of capability is something we¡¯ve come to take for granted these days.
Let¡¯s look at another example that truly is cutting-edge, this time at the intersection of local government and small business. Many metropolitan cities are supporting open data initiatives in which public data is made easily accessible through access to the databases that store this information. As an example, let¡¯s look at Los Angeles building permit data, business listings, and census data.
Imagine you work at a real estate investment firm and are trying to find the next up-and-coming neighborhood. You could use SQL to combine the permit, business, and census data in order to identify areas that are undergoing a lot of construction, have high populations, and contain a relatively low number of businesses. This might be a great opportunity to purchase property in a soon-to-be thriving neighborhood! For the first time in history, it¡¯s easy for a small business to leverage quantitative data from the government in order to make a highly informed business decision.
Leveraging SQL to Boost Your Business and Career
There are many ways to harness SQL¡¯s power to supercharge your business and career, in marketing and sales roles, and beyond. Here are just a few:
Increase sales: A sales manager could use SQL to compare the performance of various lead-generation programs and double down on those that are working.
Track ads: A marketing manager responsible for understanding the efficacy of an ad campaign could use SQL to compare the increase in sales before and after running the ad.
Streamline processes: A business manager could use SQL to compare the resources used by various departments in order to determine which are operating efficiently.

¡°Data scientist¡± is one of today’s hottest jobs.
In fact, Glassdoor calls it the best job of 2017, with a median base salary of $110,000. This fact shouldn¡¯t be big news. In 2011, McKinsey predicted there would be a shortage of 1.5 million managers and analysts “with the know-how to use the analysis of big data to make effective decisions.” Today, there are more than 38,000 data scientist positions listed?on Glassdoor.com.
It makes perfect sense that this job is both new and popular, since every move you make online is actively creating data somewhere for something. Someone has to make sense of that data and discover trends in the data to see if the data is useful. That is the job of the data scientist. But how does the data scientist go about the job? Here are the three skills and three tools that every data scientist should master.
Data science is ¡°one of the hottest and best-paid professions in the U.S.¡± More than ever, companies need analytical minds who can compile data, analyze it, and drive everything from marketing forecasts to product launches with compelling predictions. Their work drives the core strategies of modern business ¡ª so much so that, by 2018, data-related job openings will total 1.5 million. That¡¯s why we¡¯ve worked hard to develop classes, workshops, and courses to confront the data science skills gap. The latest addition to our proud family of data education is the new Data Science Immersive program.
Launching for the first time in San Francisco and Washington, D.C. on April 11, this full-time Immersive program will equip you with the tools and techniques you need to become a data pro in just 12 weeks.
The Data Journalists handbook defines data literacy as, ¡°the ability to consume for knowledge, produce coherently and think critically about data.¡± It goes on to say that ¡°data literacy includes statistical literacy but also understanding how to work with large data sets, how they were produced, how to connect various data sets and how to interpret them.¡±
At 足球竞彩网 Assembly, we¡¯d like to imagine a world where you don¡¯t need a Ph.D. in Statistics to have a data-informed conversation about your business, your health, or your life in general. Over the past year, we¡¯ve embarked on the journey to build a more data literate world through education offerings that meet the diverse needs of our students.
In building these courses, we’ve sought advice from data scientists, analysts, and hiring managers to determine the critical skills you need to become data literate in today¡¯s workforce. We discovered that it isn¡¯t just a concrete list of skills, but a mindset geared towards data¡ªa way of approaching problems beyond ¡°gut instincts.¡±?
Here, we’ve proposed a few simple questions that will help you start to view the world through the lens of data.
