An item analysis helps to determine if items on a test are measuring the same construct. This is important for assessing construct validity, which refers to the extent to which a test measures the construct or concept it is supposed to measure. By analyzing how each item relates to other items on the test and to the overall construct being measured, researchers can determine if the test accurately assesses the intended construct.
