In situations where none of the simpler tests are applicable:

- Bartlett's Correction to Wilk's Lambda for MANOVA is used on crosstabs of Categorical Questions by other Numeric Questions. If
**Statistical tests for categorical and numeric data > Means**is set to**Non-parametric**each of the numeric variable is replaced by its ranks (computed within variable with ties replaced by their mean rank). - Bartlett's Chi-square for Canonical Correlation is used on crosstabs of Numeric Questions, or, where the categorical variables are not mutually exclusive. The
**Correlations**setting determines how the correlations are computed (e.g., if set to Pearson's Product Moment Correlation the test is parametric; otherwise it is nonparametric - see Correlations - Comparing Two Numeric Variables ). - Pearson’s Chi-square for Canonical Correlation Analysis is used on crosstabs of Categorical Questions.
