The construction of a Thurstone Equal Appearing Interval attitude scale involves a specific sequence of steps designed to create a measurement tool where the intervals between scale points are perceived as equal by respondents. Let's analyze the correct order:
Steps for Thurstone Scale Construction
The correct sequence follows Option B, which represents the standard procedure:
- A. Collection and Editing of items: This initial phase involves gathering a large number of statements related to the attitude being measured and refining them for clarity and relevance.
- D. Sorting items on different continuum: Judges are presented with the edited items and asked to sort them into a predetermined number of ordered categories (usually 11) representing different degrees of the attitude.
- B. Calculating Scale and Q values: Based on the judges' sorting, a scale value (typically the median rank) and an index of ambiguity (usually the interquartile range, or Q-value) are calculated for each item.
- C. Finalization of items: Items are selected for the final scale based on their scale values and low ambiguity (Q-values). The goal is to choose a set of items that are roughly equally spaced along the attitude continuum.
Step E, Administration, occurs after the scale has been constructed and finalized; it is not part of the construction process itself.
Therefore, the correct sequential steps are A, D, B, C.
