Open-ended questions
(the respondent writes out an answer in a blank space) are easy to ask and difficult to analyze.
It is much easier to collect and analyze data when respondents choose a specific answer
(closed-ended; includes yes/no questions, multiplechoice, Likert—scales—ratings 1 to 5, etc.).
For example, If you want to know how much time people spend reading each day, try to give them categories to select
(less than 30 minutes, 30-60 minutes, etc.).
