Question

Quizplus · Accepted Answer

Internal consistency refers to the degree to which the items in a scale measure the same construct. Therefore, David's concern about whether his items are measuring the same thing is an issue of internal consistency. Option B, external validity, refers to the degree to which the findings of a study can be generalized to other populations or settings. Option C, test-retest reliability, refers to the degree to which the same results are obtained when a measure is administered multiple times. Option D, internal validity, refers to the degree to which a study accurately measures the relationship between two variables without being influenced by other factors. While all of these concepts are important in scale development, the best answer for this scenario is A.
