For one online questionnaire, I received many responses. some people did not fill the complete questionnaire. is there any benchmark to include or exclude some response for data analysis? any references form the literature? Thank you.
Thank you Sir, I did not marked compulsory just to get more responses & make it easy for respondents [just in case they want to leave, they leave their done response] .
Now i want to exclude responses where respondents respondents again only 50% questionnaire.
Is there any reference which says you can include 50%, 80% filled questionnaire?
