In the example above, our new question would be What influences Survey Scores to increase/decrease?. The biggest difference between analyzing a measure/summarized column and an unsummarized numeric column is the level at which the analysis runs. Decomp trees analyze one value by many categories, or dimensions. The analysis is as follows: Top segments for numerical targets show groups where the house prices on average are higher than in the overall dataset. Its hard to generalize based on only a few observations. You can switch from Categorical Analysis to Continuous Analysis in the Formatting Pane under the Analysis card. Left pane: The left pane contains one visual. Microsoft Power BI Ultimate Decomposition Tree Visualization Measures and summarized columns are automatically analyzed at the level of the Explain by fields used.
