What is validity?
Degree to which an instrument measures what it is supposed to measure

- Content validity
- Construct validity
- Concurrent validity
- Predictive validity
Also called as logical validity
- experts validate instrument
- appears to measure the variable being studied
Face validity
Covers a representative sample of variables
Content validity
Is able to predict results similar to those of a test already validated in the past
Concurrent validity
Produces results similar to the instruments in the past that will be employed in the future
Predictive validity
What is reliability?
Refers to the consistency of measures or accuracy of the measurement
What are the four types of reliability
- Test retest
- Parallel forms
- Internal consistency
- Inter-rater reliability
Giving the same test to the same group of respondents twice
Test-retest
Also called equivalent forms reliability
- administer two identical tests except for wordings to the same group of respondents
