To follow along in the Power BI service, download the Customer Feedback Excel file from the GitHub page that opens. I see a warning that the metric I'm analyzing has more than 10 unique values and that this amount might affect the quality of my analysis. It uses artificial intelligence (AI) to find the next dimension to drill down. So the insight you receive looks at how increasing tenure by a standard amount, which is the standard deviation of tenure, affects the likelihood of receiving a low rating. All the other values for Theme are shown in black. For example, we have Sales Amount and Product Volume Qty as measures. It automatically aggregates data and enables drilling down into your dimensions in any order. Only 390 of them gave a low rating. Assuming we have the data in the report, the first step is to add a decomposition tree to the report layout. The biggest difference between analyzing a measure/summarized column and an unsummarized numeric column is the level at which the analysis runs. In this case, 13.44 months depict the standard deviation of tenure. But if we select April in the bar chart, the highest changes to Product Type is Advanced Surgical. How do you calculate key influencers for numeric analysis? It automatically aggregates data and enables drilling down into your dimensions in any order. When a level is locked, it can't be removed or changed. Learn about everything else you can do with decomp trees in Create and view decomposition tree visuals in Power BI.
