Difficulty index
Indicates percentage of people who answered each item correctly
Normative & Ipsative format
Normative - person's score evaluated by comparing it to others who took same test
Ipsative - measures compare traits within same person
Achievement (attainment) tests vs. personality (interest) inventory
Achievement - Measure maximum performance or present level of skill
Personality - typical performance
Q-sort
Sorting statements to evaluate self-esteem
Sprial test vs. cyclical test
Spiral - Items get progressively harder
Cyclical - several sections which are spiral
Test battery
Horizontal test - measures various factors (ex: math & science) during same testing procedure
Which is more important, validity or reliability?
Validity - a test must measure what it means to measure
Types of validity
Content - does the test examine the behavior under scrutiny?
Construct - test's ability to measure a theoretical construct like intelligence
Concurrent - how well the test compares to other instruments that are intended for the same purpose
Predictive (empirical) - test's ability to predict future behavior according to criteria
Consequential - social implications of using tests
* criterion validity - concurrent validity and predictive validity together
Incremental vs. synthetic validity
Incremental - process by which a test is refined and becomes more valid as contradictory items are dropped
Synthetic - helper looks for tests that have been shown to predict each job element or component
Convergent vs. discriminant validity
Convergent - correlating test scores with an outside source
Discriminant - test will not reflect unrelated variables
Reliability coefficient of .70 means
70% of the score is accurate and 30% is inaccurate
True variance or coefficient of determination
Square the coefficient
Ex: Correlation of .70 .... .70 x .70 = .49 and .49 x 100 = 49%
