What is Reliability “consistency”
This is the tendency of a test to produce the same scores again and again. Types:
- Test-Rest Reliability
- Split Half Reliability
What is Test-Retest Reliability
This is best for intelligence, this is when you administer a test twice at two different points in time.
What is Split Half Reliability
This is when you compare the result of the first half of your test to the second half of the test.
What is Validity
This is the degree to which a test actually measures what it is supposed to measure. Types
- Content Validity
- predictive Validity
What is Content Validity
