Question | Answer |
variables | aspect of testing conditions that can change or take on different characteristics with different conditions |
IV | random |
dv | measured |
subject | quasi, gender |
confounded | another subject covarrying |
extraneous | factor we didnt think about |
operational definition | statements of the precise meaning of procedures or concepts within an experiment; includes iv and dv |
converging operations | using different operational definitions to arrive at the same meaning of a concept |
iv | conditions manipulated by the experimenter |
confound variable | another variable that varies systematically with the iv such that possible effects of this variable cannot be separated from the iv |
dv | measure of behavior, outcome variable |
frequency | # of times a behavior occurs |
rate | # behaviors relative to time |
duration | time the behavior lasts |
latency | delay until onset of behavior |
topography | style/quality of behavior |
force | intensity of behavior |
locus | location where behavior occurs |
categorical variable | varies in kind |
quantitative var | varies in amount |
discrete | distinct categories or whole units |
continuous | allow for meaningful partial/fractional units |
apparent limits | the individual points on a scale of measurement |
real limits | the real interval represented by that # |
nominal | naming categorical variables |
ordinal scale | ranking categorical variables |
interval | measuring units |
ratio | measuring units, including zero |
error variance or random error | variability in the dv not associated with the iv |
systematic error | error due to some consistent bias |
reliability | degree to which a measurement gives the same result on different occasions |
test retest reliability | test gives the same score on different occasions |
internal consistency | different items on a test measure the same idea |
measurement validity | degree to which a measurement tests what its supposed to test |
construct validity | idea that a test measures the theocratical construct that its supposed to measure and not something else |
face validity | test seems valid superficially |
content validity | tests measures the full range of the construct |
criterion validity | test correlates with other tests of same construct |
concurrent validity | similar scores on different iq test at same time |
predictive validity | depends on outcome |
