Measurement involves assigning symbols to phenomena to characterize it precisely. Evaluation determines how well educational objectives are realized. Measurement is part of evaluation by providing quantitative data like percentages and averages. Evaluation judges measurement data and determines if outcomes are good, bad or average. The key difference is that measurement provides quantitative data while evaluation makes qualitative judgements about the data and educational outcomes.

- 2. MEASUREMENTMEASUREMENT According to Bradfield, “Measurement is a process of assigning symbols to the dimensions of phenomenon in order to characterize the status of the phenomenon as precisely as possible.”
- 3. Functions of Measurement According to Lee J. Cornbach (1949) • Prognosis Function • Diagnosis Function • Research Function
- 4. EVALUATIONEVALUATION • “Evaluation is the process of determining to what extend the educational objectives are being realized.” - Ralph Tyler
- 5. Aim of EvaluationAim of Evaluation Main aim of Evaluation is to improve educational program of the school and to make it more effective.
- 6. Functions of EvaluationFunctions of Evaluation Educational Evaluation can be considered a process of determining:- 1. The extend and how well an educational objective is being attained. 2. The effectiveness of teaching- learning experience provided in the classroom.

- 9. 3. Diagnostic Evaluation (learning difficulties) 4.Summative Evaluation (product evaluation)
- 10. Need and Importance ofNeed and Importance of EvaluationEvaluation To fulfill classroom objectives To diagnose learning difficulties of students To determine readiness for new learning experiences To form students' classroom groups for special activities To assist students in their problems of adjustment To prepare reports of pupils' progress
- 11. RELATIONSHIPRELATIONSHIP When we assign a score on a given task performed by a learner, we are doing an act of measurement. When we compare this score with those of other learners and judge whether it is good/bad/average or satisfactory/unsatisfactory, we are doing an act of evaluation
- 12. Measurement is a part of process of Evaluation Measurement is that part of Evaluation which is expressed in percentage, quantity, digits, mean and average. Evaluation depends upon measurement but it is not synonymous to it.
- 13. Evaluation encompasses but goes beyond the meaning of the terms “test” and “measurement”
- 14. Sound evaluation is based upon the results of accurate and relevant measurement. Measurement gives an evaluator a quantitative description. Measurement is only a tool to be used in evaluation, by itself it is meaningless
- 15. DIFFERENCES
- 19. Sound Evaluation is based upon the results of measurement. The judgement based upon the measurement is termed as evaluation
