Final Answer:
Paraphrase: Composite scales, also known as summated rating scales, refer to a measurement technique that combines multiple items or questions into a single score to assess a particular construct.
Step-by-step explanation:
Composite scales, often termed as summated rating scales, are a methodological approach used in research and measurement. Here's a detailed breakdown:
Combining Multiple Items:
These scales involve amalgamating various items or questions that collectively measure a specific construct or variable. For instance, in a survey about job satisfaction, questions related to work environment, salary, and colleague relationships may be combined into one composite scale.
Scoring Mechanism:
Each item within the scale contributes to the overall score. Participants' responses to individual questions are aggregated to form a comprehensive assessment. This allows for a more nuanced and comprehensive understanding of the targeted concept.
Reliability and Validity:
The reliability and validity of composite scales are crucial considerations. Researchers aim to ensure that the scale consistently measures the intended construct (reliability) and accurately captures the concept it is supposed to represent (validity).
Common Usage:
Composite scales are widely employed in various fields, including psychology, sociology, and market research. They offer a practical way to simplify complex data while preserving the essential information needed for analysis.
