Measures split-half reliability by estimating the average correlation that would be obtained by considering every possible way to split the test in half; can be used when there are more than two response alternatives is also known as Cronbach's alpha.
It can also be known as coefficient alpha, Guttman's, Hoyt method and KR-20. This measure is also expected to show the correlation between two tests with the same constructs.
