Which of the following is a method of estimating reliability coefficient of a test?

1. Parallel form
2. Split-half technique
3. Rational equivalence

Exam Year(s)

DSSSB PGT - 2023,

Answer: D

All three are methods of estimating reliability. The parallel (alternate) form method correlates scores on two equivalent forms of the test. The split-half technique correlates two halves of one test. The rational equivalence method (the Kuder-Richardson approach) estimates reliability from the inter-correlation of the items. So the options listing fewer than all three are incomplete.

A fourth way is the test-retest method, in which the same test is given twice to the same people and the two scores are correlated.

Which of the following is assessed when a test is divided into two equal halves employing odd even method (items 1, 3, 5- in one group and items 2, 4, 6- in another group) and correlation is computed between the scores of odd and even items?

Exam Year(s)

DSSSB PGT - 2023,

Answer: C

Dividing a test into two equal halves by the odd-even method and correlating the scores on the two halves assesses internal consistency, which is whether the items of the test measure the same thing. It is the split-half method of reliability. Correlational validity and criterial consistency are not the name of this check, and 'critical consistency' is not a psychometric term.

Odd-even splitting is preferred to a first-half, second-half split because fatigue and practice effects are spread equally between the two halves.

The cards of Rorschach Inkblot test are presented to the subject in two phases. Which of the following pairs suggests the exact nomenclature of these phases?

Exam Year(s)

DSSSB PGT - 2023,

Answer: B

The Rorschach cards are presented in two phases, the performance proper (the subject says what the blot looks like) and the inquiry (the examiner asks where in the blot the person saw it and what made it look so). 'Understanding' and 'reporting' are not the names of the phases, so the other pairs are wrong.

Which of the following is the important concern of psychology in regard to psychological testing?

Exam Year(s)

DSSSB PGT - 2023,

Answer: B

The important concern of psychology in regard to psychological testing is the assessment of individual differences, that is, how people differ from one another in abilities, personality and other attributes. Individual capabilities and individual performance are particular things that tests may measure, and ethical issues are a concern of test use, not the main purpose of the testing.

Tests are used to compare people on the same attribute, so the aim is to show differences between persons and not just one person's score.

Which of the following scales are designed to provide a quantitative measure of the individual's relative position along an unidimensional continuum?

Exam Year(s)

DSSSB PGT - 2023,

Answer: B

Attitude scales are designed to give a quantitative measure of an individual's relative position along a single (unidimensional) continuum, from very unfavourable to very favourable towards an object. Examples are Thurstone's and Likert's scales. Aptitude, interest and personality scales deal with several dimensions or kinds of scores rather than one continuum.

Thurstone and Likert scales place a person along a single line from favourable to unfavourable, which is the unidimensional continuum of the stem.

The responses of a psychological test, which are given in scaled form, generally indicate what among the following?

Exam Year(s)

DSSSB PGT - 2023,

Answer: D

The key gives strength and magnitude of the responses. When responses to a test are given on a scale, such as 'strongly agree' to 'strongly disagree', each response shows how strong or intense the respondent's reaction is. Reliability and validity belong to the test as a whole and are not shown by individual scaled answers. The key's choice of 'responses' over 'items' is because it is the answer of the person that carries the scale value.

Scaled responses, such as a five-point scale, show how strongly the person agrees, which is the strength and magnitude of the response.

Psychological measurement does NOT include which of the following properties?

Exam Year(s)

DSSSB PGT - 2023,

Answer: D

The property that is NOT part of psychological measurement is that it "always measures the constructs with objectivity". Measurement means assigning numbers to attributes by rules, it is always about some attribute or feature of the object, and it involves quantification. But psychological constructs such as intelligence or anxiety are measured indirectly, with error, so objectivity is something a test aims for and reports through reliability and validity; it is not guaranteed in every measurement.

Which of the following psychological tests is useful for assessing individual differences in several motives?

Exam Year(s)

DSSSB PGT - 2023,

Answer: B

The Thematic Apperception Test is useful for assessing individual differences in several motives, such as achievement, affiliation and power, from the stories a person tells about pictures. The Rorschach inkblot test is mainly for personality structure, the MMPI is a self-report inventory for psychopathology, and the Stanford-Binet scale measures intelligence. In the TAT the person makes up a story for each picture, and the stories are scored for needs such as achievement, affiliation and power, which makes the test a measure of several motives.
