Quizplus · Accepted Answer

Split-half reliability tends to underestimate the true reliability of the full test without correction. This is because the two halves may not be equivalent or may not measure the same construct equally. Correction methods, such as the Spearman-Brown prophecy formula, can be used to improve the accuracy of split-half reliability estimates.
