How well a study's findings can be applied to other people and circumstances. a definition of a construct that describes the operations to be carried out in order for the construct to be measured empirically. specify the domain of the construct 2.) ability of a measure to obtain similar scores for the same object, trait, or construct across time, across different evaluators, or across the items forming the measure. Criterion-related validity is concerned with the relationship between individuals' performance on two measures used to assess the same construct. In research, internal validity is the extent to which you are able to say that no other variables except the one you're studying caused the result. This is the least sophisticated measure of validity. In science, the idea is similar, but the definition is much narrower. the extent to which differences in scores on a measuring instrument reflect true differences among individuals, groups, or situations in the characteristic that it seeks to measure, or true differences in the same individual, group, or situation from one occasion to another, rather than systematic or random errors.

Face validity is simply whether the test appears (at face value) to measure what it claims to. assess validity. Validity Validity refers to the similarity between the experiment value and the true value. External validity is about generalization: To what extent can an effect in research, be generalized to populations, settings, treatment variables, and measurement variables?External validity is usually split into two distinct types, population validity and ecological validity and they are both essential elements in judging the strength of an experimental design. It is important that measures of concepts are high in content validity. measurement in which numbers are assigned to objects or classes of objects solely for the purpose of identification.

For example, the weight of 1 mole of carbon should be 12g, but when we are measuring it could take different values depending on the Does it measure what its suppose to. Predictive validity is regarded as a very strong measure of statistical validity, but it does contain a few weaknesses that statisticians and researchers need to take into consideration.. Predictive validity does not test all of the available data, and individuals who are not selected cannot, by definition, go on to produce a score on that particular criterion. specify the domain of the construct 2.)
