Which of the following formula is used to determine reliability by the split-half method?
Answer: A
The Spearman-Brown formula is used to estimate reliability by the split-half method, because correlating two halves of a test gives the reliability of only half the test length, and the formula steps this up to the full length. The Kuder-Richardson formulas and Cronbach's alpha measure internal consistency from all items, and there is no 'Wallis-Richardson formula' for reliability.
The split-half correlation is for half-length tests only, so the Spearman-Brown formula, r = 2r(hh) / (1 + r(hh)), is applied to find the reliability of the full test.
