The researchers assumed that older adults are different from younger adults in their suicidal ideation and in their reasons for thinking about committing suicide because of differences in life experiences and coping competence. Hence, they used cross-sectional research and recruited 150 older adults (60–95 years) who were matched with 150 younger adults (17–34 years) on gender, ethnicity, religion and self-reported health status. Beck's scale for suicidal ideation was used to measure suicidal ideation. They used a 't' test for comparison of variables and found no significant difference. According to Siegler, neither cross-sectional nor longitudinal studies provide much information about how those changes occur over time. He discussed a method that involves carefully observing behaviour during periods when rapid change is occurring and collecting both quantitative and qualitative information.
What is the df for the 't' test used here
Correct answer: D. 298
Two groups of 150 compared with an independent t-test: df = 150 + 150 − 2 = 298.
When null hypothesis is false and we are accepting it then we make
Correct answer: B. Type II error
Accepting (failing to reject) a false null hypothesis is a Type II error.
One psychologist while collecting data from gamblers, first identified one gambler and from him traced out three more; and through these three further more. He continued like this, This is an example of
Correct answer: C. Snowball sampling
Locating participants through referral chains (one gambler leads to three more) is snowball sampling.
Parameter : population :: ______ : sample
Correct answer: C. Statistic
A parameter describes a population; a statistic describes a sample.
Which of the following is considered to be error component in ANOVA ?
Correct answer: B. Within mean square
In ANOVA the within-groups mean square is the error term.
Which of the following software is used extensively for analysis of qualitative data by researchers in psychology ?
Correct answer: C. N-VIVO
NVivo is widely used for qualitative data analysis; SPSS, AMOS and LISREL are quantitative.
To calculate the correlation between a genuinely dichotomus variable and a continuous variable we have to use
Correct answer: B. Point-biserial 'r'
Point-biserial r correlates a genuinely dichotomous variable with a continuous one.
Which scale of measurement has absolute zero ?
Correct answer: D. Ratio
Only the ratio scale has a true (absolute) zero.
What is true about retrospective studies ?
(A) Data are often collected with the help of narrative methods
(B) It is also knows as naturalistic inquiry
(C) Collected data can be analysed through
(D) It is same as quasi-experiment
(E) Biographical research is a good example of retrospective study
Choose the correct answer from the options given below :
Correct answer: C. (A), (C), (E) only
Retrospective studies use narrative data, can be analysed qualitatively and include biographical research; they are not quasi-experiments.
What is true about multiple regression ?
(A) There can be more than two criterion
(B) There can be more than two predictors
(C) It indicates linear relation between one predicator and one criterion
(D) The equation for regression line contains partial regression coefficients
Correct answer: C. (B), (D) only
Multiple regression has two or more predictors and one criterion; its equation uses partial regression coefficients.
How type IJ error can be reduced while testing hypothesis ?
(A) Decreasing the chosen level of significance
(B) Increasing the chosen level of significance
(C) Decreasing the sample size
(D) Increasing the sample size
Correct answer: B. (B), (D) only
Type II error falls when α is raised and when the sample size (power) is increased.
Match List-I with List-II.
Correct answer: C. A-III, B-IV, C-I, D-II
Coefficient of dispersion – variance relative to the mean; SD – positive square root of variance; CV – SD as a percentage of the mean; variance – mean of squared deviations.
In one Exploratory sequential design what would be the correct sequence ?
(A) Quantitative Data Collection
(B) Qualitative Data Collection
(C) Quantitative Data analysis
(D) Qualitative Data Analysis
(E) Interpretation
Correct answer: D. B, D, A, C, E
Exploratory sequential mixed design: qualitative collection → qualitative analysis → quantitative collection → quantitative analysis → interpretation.
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as
Reason (R).
Assertion (A): The researcher manipulating one or more variables is called an experiment.
Reason (R); A research design is one in which a variable is manioulated with a goal of identifying the causes of events is called experimental design
In the light of the above statements, choose the most appropriate answer from the options given below :
Correct answer: A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
An experiment is research in which the investigator manipulates variables to identify causes, which is exactly what an experimental design is.
A researcher studied the variables that determined Post-Traumatic Growth (PTG) in the husbands of breast cancer survivors. The existing literature identified a number of factors such as emotional support, quality of marital relationship and exposure to individuals with PTG as important determinants of PTG in women. No information was available on PTG of the husbands of the patients. The researcher investigated the same factors influencing their husbands.
What is the design used by the researcher ?
Correct answer: A. Correctional design
The study relates naturally occurring factors to PTG without manipulation — a correlational design (printed as 'correctional').
What type of statistical analysis should be used by the researcher address his objective ?
Correct answer: C. Regression Analysis
Predicting PTG from several determinants calls for regression analysis.
What is the criterion variable in this study ?
Correct answer: C. Post-traumatic growth
Post-traumatic growth is the criterion (outcome) variable.
Which of the following will be the correct hypothesis for the study ?
Correct answer: A. The emotional support, quality of marital relationship and exposure to individual modeling of PTG will all contribute husband's experience of PTG
Based on the literature, the hypothesis is that emotional support, marital quality and exposure to people with PTG will contribute to the husbands' PTG.
To conduct a study on Anganwadi workers, the researcher randomly selected five districts out of 30 districts of a state and collected data from each and every Anganwadi worker from these five districts. This is an example of
Correct answer: B. Cluster sampling
Randomly selecting whole districts and studying every worker in them is cluster sampling.
One sports psychologist wanted to carry out a biographical study by writing and recording the experiences of a hockey legend. This is an example of ______ approach.
Correct answer: C. Narrative study
Recording and retelling one person's life experiences is a narrative (biographical) study.
"The present article describes a qualitative study of the career development of 16 prominent, highly achieving Indian women across six occupational fields. Our overall aim was to explore critical influences on the career development of these women, particularly those related to their attainment of professional success." The above-mentioned purpose statement indicates a:
Correct answer: B. Grounded Theory Study
Exploring the critical influences on career development to build an explanatory model reflects a grounded-theory purpose.
Note: standard textbooks differ on this one — cross-check with NTA's final answer key.
Standard deviation of sampling distribution is known as
Correct answer: B. Sampling error
The SD of the sampling distribution is the standard error — a measure of sampling error.
A basic set of beliefs that guide action is called:
Correct answer: B. Paradigm
A paradigm is a basic set of beliefs that guide action (Guba).
Which of the following should be assured before going for parametric analysis of variance?
A. Independence of scores of the subjects
B. Categorical dependent variable
C. Random assignment of subjects to the treatments
D. Homogeneity of variance of the subjects' scores
Choose the most appropriate answer from the options given below:
Correct answer: C. A, C, D only
ANOVA assumes independent observations, random assignment and homogeneity of variance, with a continuous (not categorical) DV.
Which of the following are true about Multiple Regression?
A. It is linear regression
B. There are more than one criterion.
C. There are more than one predictor
D. It doesn't have intercept constant.
Correct answer: B. A, C only
Multiple regression is linear regression with more than one predictor (one criterion) and an intercept.
