MANOVA calculator for two dependent variables
For every group paste X and Y in matching observation order.
Group means for X and Y
| Group | n | Mean X | Mean Y |
|---|---|---|---|
| Fill in the fields above — the result is computed on this page. | |||
How do I use this page?
- Paste paired X and Y values for at least two groups.
- Review means, scatter plot and Wilks' lambda.
- Assess assumptions and plan follow-up analysis.
What this page does not do: This version supports two outcomes and up to four groups. The approximation assumes independent observations, reasonable multivariate normality, similar covariance matrices and a nonsingular E matrix.

Theory — what is a MANOVA calculator for two dependent variables?
A MANOVA calculator for two dependent variables checks whether the mean vectors of several groups differ jointly across two related outcomes, X and Y. For each group you need to paste both variables in matching observation order. A Wilks' lambda close to 1 indicates little difference relative to within-group variability, while a smaller lambda points to a larger multivariate effect. The result is approximate, since lambda is converted into a chi-square statistic, and more precise methods depend on the number of groups and outcomes.
