Count the F's: Why a Sample instead of a Census?

Count the F's: Why a Sample instead of a Census?

This interactive lecture activity, created by Carolyn Cuff of Westminster College, motivates the need for sampling. "Why sample, why not just take a census?" Under time pressure, students count the number of times the letter F appears in a paragraph. The activity demonstrates that a census, even when it is easy to take, may not give accurate information. Under the time pressure measurement errors are more frequently made in the census rather than in a small sample.
