The split-half method is a quick and easy way to establish reliability. 25) should either be removed or rewritten. For example, any items on separate halves of a test with a low correlation (e.g., r =. The reliability of a test could be improved by using this method. If the two halves of the test provide similar results, this would suggest that the test has internal reliability.
A test can be split in half in several ways, e.g., the first half and the second half or by odd and even numbers. This is done by comparing the results of one half of a test with the results of the other half. There, it measures the extent to which all parts of the test contribute equally to what is being measured.
The split-half method assesses the internal consistency of a test, such as psychometric tests and questionnaires.
