Question

The scheduling issue in this scenario is an example of a situational confounding factor, as the time of day that the testing occurred was not controlled and may have affected the results. Random assignment refers to randomly assigning participants into groups, which may or may not have been done in this study. A confounding factor due to individual differences would be a factor that varies across individuals in the study and could affect the results. Randomization error refers to errors that may occur when randomly assigning participants into groups, which is not relevant to this scenario.
