Data Format

Categorical data are often presented in summary form, where there is only one row in the data table for each combination of levels of the Y and X variables. In this situation, use the Freq or Weight variable to indicate the number of observations that each row represents. For an example of summarized categorical data, see Example of Analysis of Means for Proportions.
