3. fMRI A:\

4. Standardization Two types: –Administration and scoring –Sampling Reliability: –Is a test consistent? Test-retest Inter-rater Validity –Is the test measuring what it purports to measure?

5. Important note: We can have reliability without validity But We cannot have validity without reliability.
