Who is the proponent of the Summated Rating Scale method?
Detailed Explanation
📌 Core Theoretical Concept:
The Summated Rating Scale method was developed by Rensis Likert, famously known as the 'Likert Scale'. This psychometric scale is widely used in psychology, education, and sociology to measure an individual's attitudes, opinions, or beliefs. In this method, respondents are presented with a series of statements and asked to indicate their level of agreement or disagreement on a balanced rating scale (e.g., Strongly Agree, Agree, Neutral, Disagree, Strongly Disagree). The individual scores from each item are then summated to produce a total score that measures the overall attitude strength.
📊 Key Exam Points:
- Likert Scale is a widely adopted psychometric tool converting qualitative attitudes into quantitative metrics.
- B. F. Skinner is renowned for formulating the Theory of Operant Conditioning.
- E. L. Thorndike is famous for the Trial and Error Theory and laws of learning.
- Charles Spearman proposed the Two-Factor Theory of Intelligence (General 'g' factor and specific 's' factor).

Deep Pedagogical Analysis:
Questions regarding psychological tests, scales, and their originators frequently appear in teacher eligibility tests like CTET, UPTET, and various state TETs. Likert's summated rating scale is favored in educational evaluation due to its high reliability and ease of administration when assessing students' or teachers' attitudes towards educational programs. Aspirants should thoroughly distinguish between learning theorists (Thorndike, Skinner) and psychometric scale developers (Likert, Spearman) to secure full marks in methodology-based questions.
