Given below are two statements: one is labeled as Assertion A and the other is labeled as Reason R: Assertion A: To compare the means of different levels of an experimental factor, the variance between groups (MS factor) is compared with the variance within groups (MS error). Reason R: If MS factor is not significantly larger than MS error, we cannot reject the null hypothesis that all group means are equal. In light of the above statements, choose the most appropriate answer from the options given below:

A kind of independent variable (e.g., age, sex) that cannot be manipulated but is studied. III. A factor that could affect the relationship between the independent and dependent variables but is not controlled. IV. The measured effect or outcome resulting from the independent variable.
