- cultural limitations- complex scoring system - questionable norms- subjectivity of scoring- poor predictive quality- inadequate validity
reliability (def)
- consistency between two sets of scores
reliability (example)
a scale consistently weighs someone at 125 lbs
reliability (types)
- correlation coefficient - test-retest- alternate/parallel forms- split-half- ruder-richardson - coefficient alpha
validity (def)
how well the instrument measures something (reliability needed first)
validity (example)
a scale accurately weighs someone at their correct weight of 130 lbs
validity (types)
- content-related - criterion related- construct- face

alternate/parallel forms (example)
take form A then take form B right away

how consistent items on one test are together (using stats) (reliability)
internal consistency (pros/cons)
pro - no practice effects, don’t need more than one form con - ?
