I have a number of measures with 113 questions. I have set up my SPSS data window so that the first column is the subject Id and the rest are the individual quetsion numbers (e.g Q1...Q113) with applicable scores. When the subject did not answer a particular question it was left blank in the data window. How can I determine the amount of questions that were left unanswered by each subject? I need to know for each subject which questions they may have missed.
