Creating Surveys

SURVEY PLANNING

4. How do we get a representative sample?

It is extremely difficult to get a truly representative sample without doing a very time- and cost-intensive random selection of phone numbers or addresses. Survey companies can do this, but it is really not necessary. Your group can be confident in your data and stand by your claims if you sample as many different types of people within the parameters of the group you are looking at and by having enough people fill out the survey. To capture the attention of media and policymakers, a survey of at least 500 people is considered solid; having 500 to 1,000 completed surveys is even better.
