In case in each respondent have a freedom of selecting more than one option, In this this time how to represent the Data. If we are going to give a percentage value for each option the total is coming more than 100 %. How to overcome this problem?
In this case the situation seems to be solved by assigning a specific weight to every available option. The sum of the total options weight accounts for the 100%. So, when you process all respondent´s answers you will get the options with their correspondent percentage adding up to 100%. If you need to process options selected by respondent, you can take the options selected by everyone, and get the more and less voted options selection.
