Summary Statistics Source Variable

Available summary statistics depend on the measurement level of the summary statistics source variable. The source of summary statistics (the variable on which the summary statistics are based) is determined by:

• Measurement level. If a table (or a table section in a stacked table) contains a scale variable, summary statistics are based on the scale variable.
• Variable selection order. The default statistics source dimension (row or column) for categorical variables is based on the order in which you drag and drop variables onto the canvas pane. For example, if you drag a variable to the rows area first, the row dimension is the default statistics source dimension.
• Nesting. For categorical variables, summary statistics are based on the innermost variable in the statistics source dimension.

A stacked table may have multiple summary statistics source variables (both scale and categorical), but each table section has only one summary statistics source.
