Prophecy formula refers to a formula developed by Spearman and Brown that one can use to correct for the loss of reliability that occurs when the split-half method is used and each half of the test is one-half as long as the whole test. The method can also be used to estimate how much the test length must be increased to bring the test to a desired level of reliability.
