How to analyze multiple response questions in r

1. How do you calculate multiple responses?
2. How do you handle survey questions where participants select more than one response?

How do you calculate multiple responses?

Each answer point's percentage is calculated individually. To calculate the percentage of an answer, divide the number of responses to that point by the total number of responses to this multiple-choice question, and multiply by 100 (to reach the percentage).

How do you handle survey questions where participants select more than one response?

You should remove the answer completely since no statistical program will be able to measure this, unless you can divide it into two seperate questions, which shouldn't be done. Be sure to inform your participants there should be only one response per question in the beginning of the survey. Good luck!
