Questionnaires are a method for quickly and easily collecting data through multiple choice questions that respondents can answer by ticking boxes from the comfort of their own home, making them more convenient than one-on-one interviews which require travel but provide less detailed information. Questionnaires also allow responses to be anonymous, encouraging openness and honesty from participants.

1. Questionnaires
Questionnaires are a way of collecting data and information quickly and
easily.The questionnaires are usually multiple choicesquestion,where you
simply have to tick the box of the answer you want.
Questionnaires are a lot easier to do then a one to one interview because you
can do it from the comfort of your own home where as a one to one interview
you have to travel to get there however, you do not get a lot of information
back that you would get from a one to one interview because there is not as
much detail.
One other good thing about a questionnaire is that it can be anonymous, that
why people may be more open and honest.
