MANOVA
Hypothesis tests · Method and input reference
Factors use numeric category codes. Factorial ANOVA includes all interactions and Type II sums of squares. ANCOVA uses outcome, group, covariate columns and common slopes. MANOVA uses outcome columns followed by one group column. Synthetic example: 180 people across three groups: two correlated outcomes followed by group code (0–2).

When to consider it
- Compare multiple continuous outcomes jointly across groups.
Assumptions and scope
- Observations must be independent between subjects; repeated rows from one subject are not independent samples.
- Use the outcome and predictor coding required by the calculator; review missing data and model diagnostics.
Required inputs
- Data: outcome(s), then factor(s), then covariate for ANCOVA — Numeric observations; preserve the row and column structure described above.
- Number of outcome columns — Enter the method parameter described above.
Review missing values and data coding before running. Sample inputs are synthetic teaching examples.
