Choose the correct answer from the options given below:

An organizational behaviorist developed a tool to measure organizational loyalty. Arrange the following steps he must have accomplished sequentially.
A. Computing Cronbach’s Alpha
B. Establishing Percentile Norm
C. Item Discrimination
D. Exploratory Factor Analysis
E. Item Writing

Correct option is D

The process of developing a psychological measurement tool (such as a scale for organizational loyalty) follows a structured sequence:

Item Writing (E) – First Step
-The researcher creates a pool of potential items (questions/statements) based on theory and previous research.
-Items should be clear, relevant, and measurable.

Item Discrimination (C) – Second Step
-Determines which items effectively differentiate between high and low scorers.
-Uses statistical techniques like item-total correlation and discriminant analysis.

Exploratory Factor Analysis (D) – Third Step
-Identifies underlying factor structures (dimensions) within the scale.
-Helps in grouping related items and ensuring construct validity.

Computing Cronbach’s Alpha (A) – Fourth Step
-Measures internal consistency reliability (how well the items relate to each other).
-A Cronbach’s Alpha value above 0.7 indicates a reliable scale.

Establishing Percentile Norm (B) – Fifth Step
-Determines how individual scores compare to a reference group.
-Helps standardize interpretation of test scores.

Since the correct sequence follows the logical development process (E → C → D → A → B), the correct answer is Option 4.
