Tabulate
Menu location: Data_Organizing_Tabulate.
This a simple two way cross tabulation function. If you have two columns of numbers that correspond to different classifications of the same individuals then you can use this function to give a two way frequency table for the cross classification.
If you need to stratify by a third classification variable, or you want to perform analyses straight away on you cross tabulation, then please see the Analysis_Crosstabs function instead.
Example
A database of test scores contains two fields of interest, sex (M=1, F=0) and grade of skin reaction to an antigen (none = 0, weak + = 1, strong + = 2). Here is a list of those fields for 10 patients:
Sex | Reaction |
0 | 0 |
1 | 1 |
1 | 2 |
0 | 2 |
1 | 2 |
0 | 1 |
0 | 0 |
0 | 1 |
1 | 2 |
1 | 0 |
In order to get a cross tabulation of these from StatsDirect you should enter these data in two workbook columns. Then choose Tabulate from the Grouping section of the Data menu.
For this example:
Reaction:0 | Reaction:1 | Reaction:2 | |
0 | 1 | 2 | |
sex:0 | 2 | 2 | 1 |
sex:1 | 1 | 1 | 3 |
