A researcher has a limited amount of time and money, so they want to choose the research design that will require the smallest number of participants. Which statistical test would be best? The related samples t-test (because repeated measures designs require fewer participants). Both the related samples t-test and the independent samples t-test would need the same number of participants. The independent samples t-test (because independent measures designs require fewer participants). The type of statistical test you should use isn't determined by the research design.
