part 1 Multiple response sets have as many variables as the maximum of things mentioned. "Name your 3 favorite magazines." Would require 3 variables to enter. "name the courses you have taken." Would require as many variables as the maximum number that any respondent offered. [Under some circumstances you would be better off have one record per course.]
If you have a "check all that apply" or a more limited number of mentioned distinct responses, you would enter the data as multiple dichotomies (like dummy variables in the circumstance that categories are not mutually exclusive.) There would be the number of variables as things that could be checked, plus 1 to indicate that the answer was "none of these" if that was not already provided for. part 2 next message . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
