Stats Display: How many groups?

You are about to enter several sets of data for descriptive statistical analysis and display. For this to make sense you should have at least one set of data, but perhaps as many as 26 sets of data. This data will be entered either by typing it in or by "copy and paste" from some other screen.
Number of groups:

Each group of data should include at least 10 of data items (maximum: 1024).
