 Survey:  A sampling of data.

In deciding what kind of pizza to order for a birthday party, you may ask your friends what kind of toppings they prefer. This is a survey of your friends, and the topic that you are interested in is the preferred pizza toppings. This example shows two key ingredients of a survey: what you are interested in finding out and who should you ask.

  • First you must decide what you are interested in.
  • Next, what questions should you ask to investigate your ideas?
  • Then, you must decide who to interview (i.e., what type of people).
  • Finally, you must decide who to give the interviews (i.e., which people exactly).

Examples of Surveys:

  • political poll
  • marketing surveys
  • TV ratings
  • mall surveys
