A survey is
a good instrument to use when you want to find out what other
people think. When you do a survey, you can ask
the questions yourself (sort of like an interview,
but not as long), or you can print it and have people write
the answers.
Like
an interview, it is best if you know what information you are
looking for before you start! It is a good idea
to keep the survey simple, with short questions.
