Fold the page down the middle: term on the left, answer on the right
Units 1-3: Foundations, Statistics and Norms
Standardized procedure for sampling behavior and describing it with
1. Psychological test
scores or categories.
Integration of tests, interviews, observation and records to answer a
2. Psychological assessment
referral question.
Uniform procedures for administration and scoring, and the process
3. Standardization
of establishing norms.
4. Power test Items increase in difficulty with ample time; measures level of ability.
5. Speed test Easy items with a strict time limit; measures speed of performance.
6. Norm-referenced Score interpreted relative to a reference group.
7. Criterion-referenced Score interpreted relative to a fixed standard or mastery level.
8. Standardization sample Representative group whose scores form the test norms.
9. Stratified random sampling Sampling that matches population proportions on key variables.
10. z-score (X - M) / SD; mean 0, SD 1.
11. T-score 50 + 10z; mean 50, SD 10.
12. Stanine Standard nine; scores 1-9, mean 5, SD about 2.
13. Percentile rank Percentage of the norm group scoring below a given score.
14. Coefficient of determination r squared; proportion of variance shared by two variables.
15. Flynn effect Rise of about 3 IQ points per decade, making old norms too easy.
Unit 4: Reliability
16. Classical test theory X = T + E: observed score equals true score plus random error.
17. Reliability coefficient Proportion of observed-score variance due to true-score variance.
18. Test-retest reliability Correlation between scores on two administrations of the same test.
19. Alternate-forms reliability Correlation between two equivalent forms of a test.
Correlation between two halves of one test, corrected with
20. Split-half reliability
Spearman-Brown.
r' = nr / (1 + (n - 1)r); estimates reliability of a lengthened or
21. Spearman-Brown formula
shortened test.
22. Cronbach's alpha Internal-consistency estimate based on inter-item covariances.
23. KR-20 Internal-consistency formula for dichotomously scored items.
