Statistical Tests
Browser-based statistical checks for practical engineering and quality analysis. These tools are kept separate from the general Tools/App page so normality and homogeneity tests are easy to find as the test library grows.
Upload a CSV file, select a measurement column, and evaluate whether the data passes the skewness-kurtosis normality check. The histogram displays the measured data with a red normal-curve overlay.
Open Normality TestSplit sequential data into groups and evaluate variance consistency using a Levene/Brown-Forsythe-style check, along with ANOVA for differences between group means.
