Comparing performance on odd- and even-numbered items is a method for assessing internal consistency, specifically through a technique known as split-half reliability. This approach evaluates whether different parts of the same test produce similar results, indicating the test's reliability in measuring a consistent construct.  When we compare a person's scores on the odd- numbered items with scores on the even-numbered items, a reliable test yields very close to the same score for each half.
