measure consistency
simple random sampling w/ replacement
pick names/items/choices, replace, and pick again
simple random sampling w/o replacement
picks names/items/choices, DO NOT replace, list changes
face validity
the simplest form, measure APPEARS to measure what it was intended to
content validity
instrument covers “all” the elements of the concept being measure
concurrent criterion validity
compares the instrument to a similar instrument that is ALREADY known to be a valid measure of the concept of interest
predictive criterion validity
compares the results of the instrument in question w/ future results
divergent validity
looks at two instruments, the results from them should NOT correlate
convergent validity
looks at two instruments, the results from them SHOULD correlate
re-test reliability
measure is obtained by administering the same test 2x over a period of time to a group of individuals
multiple testing effect
choices may vary since test has been given already
internal consistency
evaluates the degree in which diff. test items that measure the same construct produce similar results
forward only translation approach
one-way approach from the source language to a target language
forward translation w/ testing approach
stronger than f.o.t.a.
back translation approach
appears to be stronger than the previous two approaches, but it can emphasize literal translation or linguistic equivalence
convenience sampling
*available/ accessible clients
*volunteers
proportional quota sampling
*no random selection
*proportions/percents all match
*set quota
disproportional quota sampling
*no random selection
*proportions/percents DO NOT match
*set quota
selective sampling
*ppl picked based on specific and pre-determined criteria
snowball sampling
researcher uses their OWN networks or ads to access a few KEY ppl
seeds do the recruiting
dimensional sampling
goal: reduce sample size
there will be 1 person that’s every combination of the three variables of interest
