Selecting a sample is less time-consuming than selecting every item in the population (census). Selecting a sample is less costly than selecting every item in the population. An analysis of a sample is less cumbersome and more practical than an analysis of the entire population. A Sampling Process Begins with a Sampling Frame. The sampling frame is a listing of items that make up the ______.

population

Inaccurate or biased results can result if a frame excludes certain portions of the ______.

population

Using different frames to generate data can lead to ______ conclusions.

dissimilar
