What is Tableau?
Tableau is a visual analytics platform that helps people and organizations to make the most of their data to solve business problems. Tableau was founded in 2003 which aimed at making machine learning, statistics, natural language, and smart data prep more useful to augment human creativity in analysis. Tableau was acquired by Salesforce in 2019. Today, organizations everywhere, across all industries and departments are empowering their people with Tableau to drive change with data.
In this blog, we are going to cover the conversation of Eeshani Agarwal (Data Storyteller and Data Visualization Expert (Tableau, PowerBI, VBA, SQL, Excel). Coached 9,000+ professionals & consulted 50+ Fortune 500 companies) and Ruchika Saha (an aspiring Data Scientist). Ruchika is currently pursuing a Data Science course from Ivy Professional School. Ruchika is someone who is inspired by data visualization and her work reflects it clearly. Learn from their conversation here.
Whenever we get a table from a raw dataset, it consists of dimensions and measures in the form of columns. Tableau helps us to use those data and create insights for business uses. We are going to unfold the requirements and the usage of Tableau in different scenarios. This blog is for beginners who want to start learning how to do Data Visualization in Tableau. Here we will discuss the very basics of data visualization, starting from topics like Data Transformation, Calculations and then leading to how to answer multiple questions from the Superstore dataset.
Calculations in Tableau :
Data in raw format is usually of no help as it is large in number and looks unstructured. Through calculations, we can create better insights and make data-driven decisions for the companies. See the video to understand the questions that can come up and that can help to analyze data in a much better way. In Tableau, there are two types of calculations – calculated fields and table calculations. If one has used Excel before, they might be familiar with these terms as the concept is similar. Learn how to create a calculated field here.
Difference between calculated fields and table calculations:
The difference between calculated fields and table calculations is that a calculated field does calculations on a row basis, whereas table calculations are the ones that are done while working on the visuals. For instance, using a calculated field will create another column with the raw data that can be used to make further calculations, whereas table calculations are implemented on data that is already presented as a visual (like percentage contribution, average, etc.).
