Thanks for the video! You broke down a complicated concept and made it easy to understand. I have 2 questions after watching: 1. Why was it important to identify the outliers based on individual product category? What is the difference in those two z-scores you calculated and what does that mean? 2. How do you determine what to do with the outliers after you identify them?
@chandoo_8 ай бұрын
Thank you. The analysis of outliers depends on actual business situation. But in this particular case, 1) As our products have different sales volumes (for ex. 50% dark chocolate always sells more than Almond choco), finding outlier within segment is a better way to understand what is a truly exceptional value. Same logic applies for situations like analysing daily sales (but you ran a 50% discount sale for one week in December). 2) Once you identify the outlier values, you can investigate the reasons for such low or high values. Some of these could be pure randomness, but there might a strong business driver behind it too. May be you the sales team had an exceptional week or the current promotions you ran yielded better than normal results. Hope that helps.

many thanks for this excellent video! Do you also have a recommendation for what to do if the data is not normally distributed? Thanks again!
@chandoo_8 ай бұрын
You are welcome. The outlier detection techniques can get tricky with other distributions when using Excel. You can implement KNN technique for most datasets. Please read up on this and if possible use a tool like Python to quickly identify them. Excel 365 now supports native Python code.
