General Studies · Psychometrics & Test Reliability

Internal consistency evaluates how well the items on an assessment consistently measure the same underlying construct. Arrange the following procedural steps for estimating test reliability using the Split-Half method in their logical chronological sequence: A. Apply the Spearman-Brown Prophecy Formula to mathematically adjust the correlation to estimate the full test's reliability. B. Calculate the statistical correlation coefficient specifically between the scores obtained on the two separate sections. C. Split the collected test data into two comparable halves, such as by segregating responses into odd and even items. D. Administer the complete, single assessment to the participants to obtain their overall responses. Choose the correct answer from the options given below:
