Outline of Research or Measurement
Used to gather information from large groups of people as they can be posted out, completed online or the researche could ask personally.
Closed Questionnaires = categories with tick boxes.
Open Questionnaires = more space allowed for answere, people are able to express their opinions.
+ They can be easily distributed to a large group of people.
+ They are high in reliability because they can easily be repeated.
+ They are anonymous which means that people are more likely to answer the questions truthfully , rather than answering them face-to-face in an interview.
- The respondents may not complete the questionnaires truthfully, therefore it would be low in validity.
- There could be a low response rate which means that the replies may not be representative of all who were sent the questionnaire.
- The questions could be interepted differently and could give a different response.
- People may not even be bothered to complete the questionnaire.
