Question

Quizplus · Accepted Answer

Split-half reliability is the assessment of the consistency of a measure by dividing the test into two halves and correlating the responses of one half with the responses of the other half. This method is commonly used in social psychology to ensure the accuracy of a measure. Option A, model fit refers to how well the data fits a particular statistical model, which is not relevant in this scenario. Option B, test-retest reliability, is the consistency of a measure over time, which is not being assessed here. Option D, interrater reliability, is the degree of agreement among different raters or observers, which is also not relevant in this case.
