#### Categorical variables, Cross Grid charts

When adding a background variable (Optional variable) we can output charts containing one of these values:

- Mean
- Std. Deviation
- T-test (Column Mean test)

(In this example ‘Mean’)

#### Numerical variables as variables in Grid Charts

Numerical variables can be used as primary variables in Grid Charts – even combined with Categorical variables.

For both Frequency and Cross Grid Charts the content can be either Mean or Standard Deviation.
