Thurstone is associated with which of the following?

Correct option is A

L.L. Thurstone developed the equal-appearing intervals scale (also called Thurstone scale) for measuring attitudes. This method involves having judges rate a large pool of attitude statements according to how favorable or unfavorable they are, then selecting items that are approximately equally spaced along the attitude continuum. Respondents then indicate which statements they agree with, and their attitude score is the median value of the items they endorse.

Information Booster:
1. Method of Construction: Involves judges rating statements on an 11-point scale from extremely favorable to extremely unfavorable
2. Equal Intervals: Attempts to create an interval-level scale where distances between points are psychologically equal
3. Statement Selection: Only items with high inter-judge agreement and spanning the attitude continuum are retained
4. Scoring: Respondent's score is typically the median scale value of statements they endorse
5. Historical Significance: One of the earliest systematic methods for attitude measurement, developed in the late 1920s
