Creating nets
A net is a special item that shows the number of respondents who chose one or more from a group of categories. Nets are useful in multiple response variables in which the categories fall into a number of groups (such as favorable, unfavorable, and neutral). Nets enable you to find out how many people chose one or more responses in each group. (Subtotals would tell you the total number of responses that were chosen in each group, but not how many people chose those responses.)
UNICOM Intelligence Reporter indents the categories that belong to the net.
To create nets
1 In the Variables pane, select the categorical variable that you want to change.
2 Click Variables > Edit Variable.
The Edit Variable dialog opens. It lists all the categories in the variable.
3 Select the categories that you want to include in the net (use Ctrl+click or Shift+click to select multiple categories).
4 Click Categories > Combine > Net.
This replaces the selected categories with the new net category.
If you want to retain the original categories as well as the net categories, use Categories > Combine > Net and Keep.
This adds a new net category but also retains the original categories in the table and allows variables to be included in two or more nets.
5 Edit the default description for the net.
6 Repeat the last three steps for any other nets you want to create.
7 Choose Save and Close from the toolbar.
Difference between Net and Net and Keep
When performing a simple combine (or net), you are actually deleting some elements and adding a new combine (or net) element. Considering that the elements being combined (netted) are deleted, they are not included in the calculation. As a result, the calculations for some statistics cell items (such as mean) will be changed.
When performing a combine (or net) and keep, you are simply adding a new combined (or netted) element. The default factor value of the new element is zero. Without setting a factor for the new element, the calculation result will be the same as before adding the element. If you set a factor value for the element, the statistics value changes because the newly added element is included in the calculation.
