misc Flashcards
the preferred technique for combining test scores; compensatory when a low score on one test can be compensated for by high schores on other tests
multiple regression
autocorrelation
when the dependent variable is repeatedly administered to the same subject, the correlation between the DV is called autocorrelation
Which resampling test is computed with replacements?
Bootstrapping
Which resampling test generates different subsets of the original sample without replacement?
jackknife
which resampling test begin with the original data then systematically or randomly reorder the data then calculate the appropriate test statistic on each reordering
permutation test
a researcher employs multiple methods of measurement to increase reliability by reducing systematic error. This strategy is called
triangulation
Convergent and divergent validity are types of _____validity
construct
factors increasing validity of a test
number of items increased, homogeneity of items, an unrestricted range, low ability to guess
4 types of reliability
test retest, parallel forms, internal consistency, interrater
2 ways to assess internal consistency of a test
split half reliability, kudar-richardson or cronbach’s coeffecient alpha
when calculating split half reliability, the___ __ formula is used
spearman brown prophecy formula
what type of reliability coefficient should be used for speeded tests
alternate forms of test then test retest reliability
these involve analysis of the correlation of each item with every other item in the test
kuder richardson and cronbach’s coeffecient alpha
which one to use when items are scored dichotomously…kuder richardson or cronbach’s
kudar richardson
whats the range of the standard error of measurement
minimum of 0 to max of standard deviation of the test
when a test is totally unreliable, the standard error of measurement would be equal to the ____ ___ of the test
standard deviation
3 types of validity
content, criterion related, construct
this validity addresses how adequately a test samples a particular content area
contentt validity
this validity looks at how adequately a test score can be used to infer, predict, or estimate criterion outcome
criterion related validity
2 subtypes of criterion related validity
concurrent validity, predictive validity
in ___validity, the predictor and criterion are measured and correlated at about the same time but with ___validity there is a delay between the measurement of the predictor and the criterion
concurrent; predictive
___-validity is the amount of improvement in success rate that results from using a predictor test
incremental validity
when is incremental validity highest
when base rate is moderate (.5) and selectation ratio is low (close to .1)
