Frequency Tables

This menu produces frequency counts for grouped data. The data for this menu is given by one or more factors and the frequency counts are then the number of units in each factor combination. The menu also includes facilities for producing tables classified by multiple response factors.

Available Data

This lists data structures appropriate to the current input field. The contents will change as you move from one field to the next, displaying either variates or factors. Double-click on a name to copy it to the current input field; alternatively, you can type in the name directly.

Groups

The groups are specified by one or more factors, each of which must have the same length. The

button allows multiple selections to be copied from Available Data.

Weights

A variate specifying weights to be used in the tabulation.

Display table as percentage of margin

This allows the body of the table to be expressed as percentages of the corresponding values of the selected margin. The margin to be used as the denominator can be chosen by selecting the required factor from the drop-down list.

Set Margin

Specifies whether the tables should include margins (counts over all levels of each factor).

Save Frequencies

If selected, provides a space for you to save the frequency counts into a table data structure.

Display Frequencies in a spreadsheet

If selected, the table of frequency counts will be displayed within a spreadsheet.

Multiple Response Tables

Displays two additional options for producing frequency count tables classified by multiple response factors. For more details on multiple response factors see the Form Multiple-Response Factors menu.

Pointer to factors defining multiple-responses

A pointer to factors defining the multiple responses in the table. You can form a pointer to factors for a multiple-response table using the Form Multiple-response factors menu.

Name for factors to index multiple responses

The menu generates an ordinary factor to classify the dimension of the table corresponding to the multiple responses. You can specify identifier names for these factors in the space provided.
