I didn't combine data. It was already in the correct format. I can't say what you should do because I do not know what format your data currently uses. I used the Big Class sample data set. Here it is:

I analyzed the distribution of weight and used sex for the grouping variable.

 

Please let me know if this issue of preparing the data is still unclear.

Combine the data into a single data table such that one data column identifies the original data set and the other contains the data itself. I would use Analyze > Reliability and Survival > Life Distribution. Be sure to first select the Compare tab in the launch dialog. Cast the data column in Life role and the ID column in the Grouping role. You can fit a variety of CDF models from here.

 

Here is an example.
