Homework Help: Questions and Answers: Test items that contain alternatives with five points ranging from “strongly agree” to “strongly disagree” are characterized as using this approach to scaling:
a) Guttman scaling
b) Likert scaling
c) Nielson scaling
d) Opinion scaling
Answer:
First, let’s understand what the question is about: It’s related to the type of scaling used in test items with alternatives that range from ‘strongly agree’ to ‘strongly disagree.
The scale mentioned in the question consists of five points ranging from “strongly agree” to “strongly disagree.” This is a commonly used format in surveys and questionnaires where respondents express their level of agreement or disagreement with a statement.
Given Options: Step by Step Answering
a) Guttman scaling
- This is a cumulative scaling method where items are arranged in increasing order of difficulty. If a respondent agrees with a particular item, they should also agree with all easier items. This does not fit the description given in the question.
b) Likert scaling:
- This is a psychometric scale commonly used in questionnaires, where respondents specify their level of agreement to a statement on a multi-point scale, usually ranging from “strongly agree” to “strongly disagree.” This matches the description in the question.
c) Nielson scaling:
- There is not commonly known “Nielson scaling” in the context of psychological or social research scales. This seems incorrect.
d) Opinion scaling:
- This is a vague term and not a specific type of scaling method.
Final Answer
Based on the above analysis, the type of scaling that best fits the description of having alternatives ranging from “strongly agree” to “strongly disagree” is:
b) Likt scaling
