In this tutorial, we dive into the powerful world of statistical data visualization by building a comprehensive sales dashboard in Power BI. The star of the show is the Box and Whisker chart, a custom visual that provides a deep dive into your data’s distribution, including minimum and maximum values, quartiles ($Q1$ and $Q3$), the median ($Q2$), and the average sales. Unlike standard bar charts, this visual highlights the “volatility” and “consistency” of your products, revealing that while smartphone sales are steady and high-performing, laptop sales are significantly more volatile across different cities.
You will learn step-by-step how to import your data, set up key performance indicators, and use donut charts to track sales by product and region. Most importantly, we show you how to source the Box and Whisker visual for free from the Power BI online store to unlock advanced insights—such as why the “floor” of your smartphone sales might actually outperform the average of your laptops. By the end of this video, you’ll be able to transform a simple spreadsheet of cities and regions into a professional, rounded-corner dashboard designed for data-driven decision-making.
