Are You Practicing Random Selection?
We thought this cartoon may give you a good laugh.
As you construct your research studies, be careful as you select your respondents. Random selection, or how you draw the sample of people for your study from a population, in most cases should be representative. As we have mentioned before, sampling errors are common.
To help, here are three quick ways to control sampling errors:
1. Careful sample designs
2. Large samples
3. Multiple contacts to assure representative response.
