Assessment and Testing Flashcards
test types
subjective - scorers opinion
objective
projective
subtest
ipsative measures
assess two or more desirable options and pick the one that is most preferred.
spiral test
items get progressively harder
cyclical test
several sections which spiral, get progressively harder
vertical vs horizontal test
vertical = versions for different ages or education levels horizontal = measures various factors in the same testing session
whats more important, validity or reliability
validity (valid tests must be reliable)
when to use inter-rater reliability
subjective and projective tests
reliability coefficients
.80 is acceptable (80% is accurate, 20% is not)
true variance/ coefficient of determination
reliability coefficient squared x 100
.70^2 = .49 x100 = 49%
galton
felt intelligence a unitary factor, mental abilities are genetic and run in families
guilford
thought 120 factors added up to intelligence
associated with convergent and divergent thinking
kudos richardson coefficients of equivalence
way to measure if items of the test are measuring the same thing as other items without splitting the test and correlating.
binet and simon
1904 intelligence test in france, pioneer in projective testing
IQ
mental age over chronological age times 100
MA/CA x 100
SAS
standard age score
SD = 16
M = 100
WAIS IV
test based on neurocognitive research
60 - 90 minutes
four index scores: verbal comprehensive, perceptual reasoning, working memory, processing speed
measures IQ from 40 - 160
WPPSI III
weschler preschool and primary school intelligence
4 - 6 yrs
multiple subsets
Merrill Palmer
recommended for infants and below 7 years
Merrill Palmer
recommended for infants and below 7 years
M and SD for Weschsler and Stanford Binet
Weschsler
M = 100 SD = 15
Stanford Binet
M = 100 SD = 16
Ertl
claimed he invented an electronic machine to analyze neural efficiency and take place of paper and pencil IQ tests
Cattell
fluid and crystalized intelligence
fluid = inherited, decreases with age, not dependent of outside things
crystalized = experiential, cultural, and educational interactions
Jensen
started controversy saying african americans have lower IQ scores than whites, 80% was heredity
the racist
Williams
black intelligence test of cultural homogeneity (bitch)
to show that AA would excel when given questions that would be familiar to their community
the activist
Buros
creator of the 16 PF (16 personality factor questionnaire)
factor analytic test/inventory
Myers Briggs Type Indicator
reflects work of carl jung
AARC
association for assessment and research in counseling
item difficulty
higher the number the easier the question is
