Sometimes two variables will have been set up so that they have the same Labels, but different Values associated with their labels. For example, Q1 may have 1 Yes and 2 No, while Q2 may have 1 No and 2 Yes. If Combine is used to create a Variable Set using these variables, the labels will be taken from the first of the variables, which will mean that the table provides misleading results (you will get a warning).
The solution to this problem is to:
- Recode the values so that they align. In the example above, this means replacing the Value for No with a 2 and Yes with a 1.
- Select the new variable and give it a descriptive label in Properties > GENERAL > Label in the object inspector on the right.
- Repeat steps 2 through 4 for every variable that needs to be copied.
- Select the existing variables that were not recoded, and the copies of the recoded variables and click Combine in the toolbar at the top.
The logic behind this is as follows:
- When you use Combine, Displayr does not look at the actual Values. Instead, it looks at the Source Values (i.e., the values prior to any recoding). This is often useful as it permits Combine to work even when you have recoded data such that multiple Labels share a single Value (e.g., if computing NPS).
