How can a researcher test the validity of cross-population generalizations?
A)set higher confidence intervals
B)conduct more research in other sites
C)reduce sampling error
D)select a larger sample

Question

Quizplus · Accepted Answer

To test the validity of cross-population generalizations, the researcher needs to conduct more research in other sites to collect data from different populations and compare the results. This helps to increase the external validity of the study and reduce the potential for bias or random error. Setting higher confidence intervals, selecting a larger sample, and reducing sampling error may help to improve the precision of the findings, but they do not necessarily address the issue of cross-population generalization.
