Day 6The Scientific Method and Description

AP Question of the DayWhich of the following is an example of random sampling?I. Picking out of a hat to assign each of three classes to an experimental condition.II. Having a computer generate a random list of 100 high school students.III. Approaching any 50 students during 6th period lunch.

A. I onlyB. II onlyC. III onlyD. I and IIE. I, II, and III

B. II onlyOf the 3 methods presented, only having a computer generate a random list of names is an example of random sampling. The 1st example illustrates random assignment and not random sampling. Sampling is the process of choosing a group of participants from a population. Once sampling has been completed, one might assign the participants to conditions as described in I. Finally, approaching 50 students during a lunch period does not constitute random sampling even if the person who picks people tries to do so randomly. Remember that the word random has a very specific meaning in the context of research. Random sampling means that all members of the population had an equal chance of being selected.
