A researcher wants to increase the generalizability of a planned experimental study's results. What can the researcher do, relative to sampling, that will achieve that goal?

a. Select a sample larger than that recommended by power analysis.
b. Purposively select a sample that is extremely heterogeneous.
c. Use random assignment.
d. Use random sampling.


ANS: D
Random sampling increases the extent to which the sample is representative of the target population. Good representativeness enhances generalizability of the results. Selecting a sample larger than the size recommended by power analysis results only is a larger sample, not a more representative one. Purposive selection of a more heterogeneous sample does not increase the sample's representativeness. Use of random assignment has no effect on representativeness of the sample, since it is selected before assignment occurs.
