Question

Quizplus · Accepted Answer

Dr. Xavier is computing the reliability of an intelligence test, and therefore needs to measure the consistency of the responses across different items. Cronbach's alpha and split-half are both measures of internal consistency, and would be appropriate for this purpose. Pearson's r and significant correlations are measures of association and would not be appropriate for evaluating internal consistency. Therefore, option C (Cronbach's alpha and split-half) is the best choice out of the given options.
