Q1) Did the parametric and nonparametric tests for paired data reach the same conclusion here?
No
Q2) Which of the 4 analyses is most inappropriate for the study?
A can be used for categorical variables, no problems here
B can be used for categorical variables, no problems here
D can be used for categorical variables, no problems here
C can be used for categorical variables, but its run on repeat sample or same sample, which isn't the case here. Hence, you cannot use the
McNemar' test here
Q3) Which of the 4 analyses is most appropriate for the study?
B should not be used here because some expected value is less than 5.
E11=200*392/400=196
E12=200*8/400=4
E21=200*392=196
E22=200*8/400=4
D can be used for quantitative variables better, no problems here.
Therefore, correct option is A.
Q4) There is no association between the use of OCs and incidence of endometrial cancer.
