Find out the statements which are related to different types of reliability?
Show Hint
Reliability is concerned with the consistency of a test, and different types, like test-retest, inter-rater, and split-half reliability, assess consistency under different conditions.
Updated On: Nov 21, 2025
- The same test is administered to the same people at two points in time
- Give the test once and have it scored by two scorers or by two methods
- Give the test in one administration and then split the test into two halves for scoring
- The extent to which people score on a measure are correlated with other variables

The Correct Option is A, B, C
Solution and Explanation
Step 1: Understanding types of reliability.
Reliability refers to the consistency or stability of a measurement instrument. Different types of reliability are assessed by examining how consistent the results are under different conditions.
Step 2: Analyzing the options.
- (A) Correct, this describes test-retest reliability, where the same test is given to the same people at two different times to see if results are consistent.
- (B) Correct, this describes inter-rater reliability, where the test is scored by two different scorers or using two different methods to check for consistency.
- (C) Correct, this describes split-half reliability, where a test is divided into two halves, and the scores are compared to check for consistency.
- (D) Incorrect, this describes the concept of validity, not reliability. Validity refers to how well a test measures what it is intended to measure, not consistency over time or between scorers.
Step 3: Conclusion.
The correct answer is (A), (B), (C).
