Which of the following is NOT a classification of itemized rating scales?
A) Likert scales
B) semantic differential scales
C) Stapel scales
D) perceptual scales
E) C and D
The correct answer and explanation is :
The correct answer is D) perceptual scales.
Explanation:
Itemized rating scales are tools used in research, surveys, and questionnaires to measure attitudes, opinions, or perceptions by asking respondents to evaluate an item on a scale with a set of predefined categories. These categories allow researchers to quantify subjective feelings or judgments. The main types of itemized rating scales include Likert scales, semantic differential scales, and Stapel scales. Let’s break down the answer choices:
A) Likert Scales:
Likert scales are one of the most widely used itemized rating scales. They consist of a series of statements with a scale that measures the degree of agreement or disagreement. The scale typically ranges from “strongly agree” to “strongly disagree.” Respondents select the option that best represents their opinion. This is a common example of an itemized rating scale and is primarily used to assess attitudes or opinions.
B) Semantic Differential Scales:
Semantic differential scales are used to measure the connotative meaning of objects, events, or concepts. They usually have bipolar adjectives (e.g., “good” vs. “bad,” “happy” vs. “sad”) at each end of a scale, and respondents rate the object by selecting a position on the scale that reflects their perception. This type of scale is used to assess the intensity of respondents’ attitudes or feelings about a particular concept.
C) Stapel Scales:
Stapel scales are another type of itemized rating scale used to measure attitudes and opinions. A Stapel scale presents a single adjective (e.g., “good” or “bad”) along with a numerical scale, and respondents rate an object or concept by choosing a number that represents their perception of that adjective. This is a unipolar scale, meaning it measures a single quality without the need for a bipolar adjective pair.
D) Perceptual Scales:
“Perceptual scales” is not a widely recognized or standard classification of itemized rating scales. Perception is the broader concept that can be measured using various scales, but “perceptual scales” as a standalone category does not appear in common classification systems for rating scales. Therefore, perceptual scales do not fit as a distinct classification like the other types listed above.
Conclusion:
The correct answer is D) perceptual scales because it is not a standard classification of itemized rating scales. Likert, semantic differential, and Stapel scales are established types of itemized rating scales used to measure attitudes, opinions, and perceptions.
