No comments

Have you ever wondered how to compare sales performance between two sets of weekdays?

What You Will Learn:

  1. Setting up your data source for comparison
  2. Creating calculated fields for two sets of weekdays
  3. Configuring table calculations to get only the days you need
  4. Filtering out weekends from both data sets
  5. Implementing advanced date functions for comparison
  6. Visualizing and comparing sales for both sets of weekdays

Background Context:

Tableau enables you to conduct intricate data analyses, but comparing specific sets of weekdays can be tricky. This tutorial simplifies that process, focusing on comparing the last 10 weekdays' sales with the 10 weekdays preceding them.

Have you ever heard of the "sunken cost fallacy"? If you haven't, it is where you continue a task based on previously invested resources, such as time, despite new evidence suggesting that the cost, beginning immediately, outweighs the expected benefit.

This is what nearly happened to me during Watch Me Viz. I was convinced I had created the perfect chart. That is, until comments started coming in to the contrary. I had gotten so fixated on this one chart that I thought all other ideas were inferior.

I snapped out of it eventually and turned my attention to another chart that told the story much better.

The lesson learned: be careful of, and attuned to, sunken cost.

With that, here's Watch Me Viz for you to follow along and learn lots about Tableau.
