Qualitative And Quantitative Questions

There is a distinct difference between qualitative and quantitative questions. Qualitative questions are known as open questions as there's space for everyones personal answers, such as 'what is your favourite genre of music and why?'. Therefore you get a more detailed, realistic response.
          However, a quantitative question is closed as you are given a set of answers to choose from. For example, 'what sex are you?' would have the two options 'male' or 'female'. This means that the answers are easier to collate and can be compared to each other: saving a lot of time, as all the answers are relevant to the question.
          I have chosen to do the majority of my questionnaire using quantitative questions. Although I will also include some qualitative questions, so I recieve a few more detailed responses.
