What are the consequences of failing to meet the assumptions of a parametric test when performing research?
A) If we fail to meet the assumptions of a parametric test, then we will be unable to make any inferences regarding the population.
B) If we fail to meet one assumption of a parametric test, then we cannot perform statistical analysis on the results of the study and will be limited to qualitative descriptions of the data.
C) If we fail to meet even one assumption of a parametric test, then we should perform a nonparametric test instead.
D) If the test is robust to the violation, it does not invalidate the research; however, it may make it more difficult to detect effects.

Failing to meet the assumptions of a parametric test does not necessarily mean that we cannot make any inferences or that we are limited to qualitative descriptions of the data. If the test is robust to the violation, it does not invalidate the research, but it may make it more difficult to detect effects. However, if the violation is severe, we may need to consider using a nonparametric test instead.
