1. A psychologist wanted to study marital love between husbands and wives in arranged and love marriages. Fifty arranged marriage couples and fifty love marriage couples were randomly choosen and both the husbands and wives, were administered Marital Love Scale. The data should be analysed by [DEC 2014]
(1) Factorial ANOVA for independent groups
(2) Factorial ANOVA for repeated measures
(3) Mixed factorial ANOVA
(4) Randomized one-way ANOVA
2. In a 2 × 2 factorial design, with A and B as the statistically significant. It implies that [DEC 2014]
(1) there is cross-over interaction
(2) there is disordinal interaction
(3) there is either cross-over or disordinal interaction
(4) there are both disordinal and cross-over interactions
3. A fifth test was added to an old established selection test battery of four tests. Two multiple correlations, one between a suitable external criterion and three tests of the old battery and the other between the same criterion and four tests of the new battery were computed. The significant change is R² would provide an evidence for the [JUNE 2015]
(1) predictive validity of the old battery
(2) incremental validity of the fifth test
(3) predictive validity of the new battery
(4) concurrent validity of the fifth test
4. Read each of the following two statements Assertion (A) and Reason (R) and indicate your answer using the codes given below: [JUNE 2015]
Assertion (A) In the randomised two-group designs, if the mean difference between the two groups is analysed both by t and F tests, F is always larger than t.
Reason (R) In the randomised two groups design, the t² = F.
Codes:
(1) Both (A) and (R) are true and (R) is the correct explanation of (A)
(2) Both (A) and (R) are true, but (R) is not the correct explanation of (A)
(3) (A) is true, but (R) is false
(4) (A) is false, but (R) is true
5. Match List I and List II and select the correct answer from the codes given below: [JUNE 2015]
| List I (Designs) | List II (Features) |
|---|---|
| A. Randomised block design | I. Each subject participates under all experimental conditions |
| B. Factorial design | II. Analyses the data for matched groups |
| C. Single-factor repeated measures design | III. Suitable for studying the interactions among the independent variables |
| D. Design with a covariate | IV. Employs statistical control |
Codes:
| A | B | C | D |
|---|---|---|---|
| (1) III | II | IV | I |
| (2) III | II | I | IV |
| (3) II | III | I | IV |
| (4) II | III | IV | I |
6. In a study, 25 subjects performed the same task under three conditions-relaxed, moderately stressed and highly stressed. The suitable analysis of variance was carried out. The degrees of freedom for the conditions × subjects interaction (used as an estimate of error variance) would be [JUNE 2015]

(3) 72
(4) 74
7. Which one of the following is considered as a non-parametric alternative to one-way ANOVA for independent samples? [DEC 2015]
(1) Kruskal-Wallis H-test
(2) Mann-Whitney U-test
(3) Kolmogorov-Smirnov test
(4) Friedman’s ANOVA
