I have a set of consumer feedback data in which the answer set for some questions was Agree Strongly, Agree Slightly, Disagree Slightly, Disagree Strongly and 'I do not have'. How do I exclude those that selected 'I do not have' in the categorical analysis (i.e. to find the total % overall that selected positively out of those that have the issue).
Hopefully that makes sense. An interactive explanation would be helpful please!
