In the two sets which follow, Set I gives certain terms used in research while Set II offers their description. Match the two sets.
Set I (Terms used in research)
(a) A postulate
(b) A construct
(c) Variable
(d) Systematic error
Set II (Description)
(i) It causes obtained results to vary in a particular direction
(ii) It is something which can change either quantitatively or qualitatively
(iii) It is the statement of the principle assumed, in the absence of direct evidence
(iv) Though not directly observable, is considered to exist

- A.
a) - i); b) - ii); c) - iii); d) - iv)

- D.
a) - iv); b) - iii); c) - i); d) - ii)
Show answer & explanation
Correct answer: B
CONCEPT: Research terms are matched by the role their definitions play, not by surface wording.
A postulate is an assumed principle; a construct is an inferred but not directly observable concept; a variable is a changeable attribute; and systematic error is a directional bias in results.
APPLICATION: Applying those definitions to this item gives:
Term | Key clue | Match |
|---|---|---|
A postulate | a principle assumed without direct evidence | iii |
A construct | not directly observable but considered to exist | iv |
Variable | can change quantitatively or qualitatively | ii |
Systematic error | causes results to vary in a particular direction | i |
CONTRAST: The distractor patterns fail because they move a definition away from its own research term.
A mapping that starts with a-i treats a postulate as a measurement-bias clue rather than as an assumed principle.
A mapping that places a construct with ii treats an inferred concept as an ordinary changeable attribute.
A mapping that places a variable with iii treats a measurable or classifiable attribute as an assumed principle.
A mapping that places systematic error with ii treats directional bias as ordinary variability.
Therefore the matching is a-iii, b-iv, c-ii, d-i.
