Document Summary
The extent to which a measure is free from random error. Extent to which scores in the same measure, administered at two diferent imes, are correlated. Some concepts not stable over ime: internal consistency. Extent to which all the items in a muli-item measure correlate with each other. Number of items has an inluence on the size of the coeicient: inter-rater reliability. Extent to which the raings of one or more observers correlate with each other. The extent to which measures indicate what they are intended to measure: construct validity. The match between the conceptual deiniion and the operaional deiniion. Face validity: is the extent to which the variable appears to measure what it is intended to measure. Content validity: the extent to which the measure adequately captures the domain of the construct. Convergent validity: measures of constructs that theoreically should be related to each other are, in fact, observed to be related to each other.
