role play
acting; not naturalistic
info gathering
get score move on (questionnaire)
therapeutic assess
collaborative, interactive
ideographic
individual characteristic- unique
nomothetic
universal- general population
Wundt

Galton
differences
Cattell

projective testing
inkblot test

conformity, cooperation (high)- nonverbal
individualistic
self reliance (low)- verbal
high context
what you see happening- nonverbal
low context
directly said- verbal
error
what else is influencing your test- systematic
systematic error
predictable/pattern
McDermott

equality
same test for everybody
equity
test being adjusted to be understood by peoplel
laws
rules
ethics
principles
2010 common core
every student act 2015
Daubert
scientific evidence (judge)
Frye
general acceptance (experts + judge)
informed consent
language barriers
right to test findings
you have right to know
confidentiality
safety is more important
least stigmatizing label
not labeling people
nominal
categories
ordinal
rank ordered
interval
no zero, equal intervals
ratio
true zero
most tests
ordinal-> treated as interval
raw score
unmodified
kurtosis
steepness
plat
plateau
lepto
peaked (leap)
meso
middle
normal curve
68 95 100
34 14 2
correlation coefficient
-1 and +1
0
no relationship
correlation
causation
restriction of range
weak correlations
meta analysis
relationship across studies
disadvantage
unreliable studies
trait
distinguishable- enduring
trait can stay same- interpret + defined differently
states
less enduring, depend on context
depends on what state you’re in (mental)
random error
situational noise
reliability
consistency, precision
validity
intended measure
reliability necessary- not sufficient for validity
norms
reference groups
stratified random sampling
all members of population have equal opportunity
stratified sampling
samples from subgroups
purposive sample
arbitrarily selecting sample
observed score
true score + error
random error
unpredictable fluctuations - noise
systematic error
typically constant variable
testaker variables
emotions, lack of sleep
examiner variables
training, demeanor
test retest
same people- different administrations times- same test-> stability across time
same results 6 months later
coefficient of equivalence
relationship
between various forms
parallel forms
means- variances
alternate forms
different versions of a test
split half reliability
split test- one group- same time
spearman brown formula
est internal consistency
coefficient alpha
0 -> 1
inter scorer reliability
agreement between 2+ scores
