Homogeneity Test

Upload a CSV file, choose the measurement column, select the number of sequential groups, and run a Levene/Brown-Forsythe-style variance test plus one-way ANOVA for group means.

Homogeneity Results

Groups are formed sequentially from the selected column, matching the current Streamlit test logic. The variance test uses absolute deviations from each group median, then applies one-way ANOVA to those deviations.
