Featuring Insights From Matt Brems

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 — 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.)”
