construct validity

if it measures what it was designed to measure

concurrent validity

the criterion and predictor are measured at the same time. ex. if you were trying to measure college aptitude and gave a test to college students and compared it with their current gpa

predictive validity

how well a test predicts a criterion
ex. sat-->college gpa

convergent validity

create two tests that measure the same construct and correlate them. do they correlate? if so, it has high convergent validity. ex. self report, and test.

discriminant validity

if two dissimilar constructs have a low correlation ex. tests of self esteem vs manual dexterity

criterion

the variable that the test is trying to measure. ie. intelligence

questions to ask:

multitrait multimethod

selection ratio

the proportion of applicants who are selected

base rate

the proportion of people expected to succeed if selected at random. the real value of a test comes from comparing the hit rate with the base rate.
use old records of the percentage of people who usually succeed 60%

false positive

when you got admitted but you didnt do well

false negative

when you got rejected but you would have done well

taylor-russell table

gives the likelihood that a person selected on the basis of the test will actually succeed. There is a different table for each base rate.
use old records of the percentage of people who usually succeed 60%
then use validity (gre compared with actual success)..when u use the table u arrive at 66% which is based on gre scores. is the extra 6% worth it?

Item Response Theory

a graph of probability, where the X axis is innate ability and the Y axis is probability of passing an item

three steps in test development

test construction
standardization
test revision

Rational scales

based on an underlying belief or rationale

empirical scales

rely on criterion keying for their validity (factor analysis)

Response Style

Tendency for subjects to respond to questions or test items in a specific way, regardless of the content.

response set

social desirability (marlow crowne)

stanford-binet 4th edition

level1: g
level2: crystallized, fluid, short term memory

stanford-binet 5th edition

•Fluid Reasoning

•Knowledge

•Quantitative Reasoning

•Visual-Spatial Processing

•Working Memory

wais wes.adul.intel.scale

Includes 14 separate subtests:

•Verbal tests: Information, digitspan, vocabulary, etc.

•Performance tests: picturecompletion, block design, symbol search, etc.

wisc. wais for children

5-15

•Verbal Scale (Information, Similarities,etc.)

•Performance Scale (Picture Completion,Coding, etc.)

kaufman assessment battery for children

ages 2.5-12.5
based on well articulated theory of intelligence: rational scale

Designed to minimize cultural bias

Attempts to separate fluid andcrystallized intelligence

Consists mostly of nonverbal items

Divided into mental processingsection (fluid) and achievement section (crystallized)

3 applications for item response theory

item bias analysis-seeing if items are different for males vs females
equating-equating two different tests (gre vs sat)
tailored testing-giving different people different questions based on ability. (computer adaptive)

discriminating power

the extent to which an item discriminates those who recieve high scores vs those who recieve low scores

what does a steep upward slope indicate?

that people who did well one the test(or who have high verbal ability) are much more likely to respond correctly to the item

advantages of group testing

standardization
efficiency

Group Intelligence Tests: Advantages and Disadvantages

More convenient and Economical

Examiner cannot: establish rapport, determine student’s level of anxiety, Student might not understand instructions, might be distracted by other students

criterion-related validity

The extent to which a selection tool predicts, or significantly correlates with, important elements of work behavior

individual tests

weschler, weschler for kids, stanford-binet
kaufman children

group tests

multidimensional aptitude test
sat
act
gre
asvab, gatb

multidimensional aptitude battery

just like the weschler but online version. a group test
