Each option may be used once, more than once or not at all.

1. Of 25 patients with cancer, how many can be expected to have a negative result?

2. Of 50 patients known not to have cancer, how many will have a negative result?

Option List:
A. Unpaired t test
B. Paired t test
C. Mann whitney U test
D. Wilcoxan sign rank test
E. One way ANOVA

A study was conducted to assess if BMI was higher in 200 women with GDM compared to those without. BMI and FPG were normally distributed. They estimated height, weight, Fasting plasma glucose (FPG), HbA1c, Insulin level. They also noted down family history of DM, previous history of GDM and Insulin resistance by HOMA IR.
From the above list, choose the most suitable option. Each option may be used once, more than once or not at all.

3. Which test is appropriate for establishing that BMI was in fact higher in women with GDM in the above study?

4. Which test is appropriate to find the strength of association between FPG and BMI in the above study?

5. Which study is appropriate to find the strength of association between HOMA IR and family history of GDM?

6. Which test is appropriate to quantify the strength of association between HbA1C and BMI in the above study?

Option List:
A. One sample t test
B. Multiple regression
C. Pearson correlation test
D. ANOVA
E. Chi squared test
F. Two sample unpaired t test
G. Wilcoxon sign rank test
H. Spearman correlation test
I. Mann Whitney U test
J. Mean difference
K. Percentage difference
L. Proportion
M. Coefficient of variation
N. Inter quartile range

A study was done to assess delivery time in Forceps, Ventouse and Caesarean delivery in diabetic mothers. HbA1C, Birth weight, Age, Parity, and Smoking were also recorded. Which inferential test from the above list you would select for the following.

7. To compare the weight loss in pregnant women before and after attending the healthy eating program (Not normally distributed).

8. To determine whether forceps delivery increases chances of having pelvic floor surgery later in life.

9. To compare the decision-delivery time interval in second stage for forceps, ventouse and caesarean section (normally distributed).

10. To compare the weight loss in pregnant women before and after attending the healthy eating program (Not normally distributed)
