Split Half Reliability is an internal consistency approach to quantifying the reliability of a test, in the paradigm of classical test theory. Reliability refers to the repeatability or consistency of the test scores; we definitely want a test to be reliable. The name comes from a simple description of the method: we split the test into two halves, calculate the score on each half for each ...
Split-half reliability is a statistical method used to measure the consistency of the scores of a test. It is a form of internal consistency reliability and had been commonly used before the coefficient α was invented.

A low split-half coefficient in this case would simply confirm the test's multi-dimensionality rather than indicating a lack of consistency. If a test genuinely measures multiple constructs, reliability must be calculated independently for each subscale, ensuring that each calculation pertains only to items related to a single, homogeneous trait.

Split-half reliability is a statistical measure that assesses the internal consistency, or reliability, of a psychometric test or questionnaire. It evaluates whether the items within a test are consistently measuring the same construct by splitting the test into two halves.
Split-half reliability is a measure of consistency applied within the field of psychology to assess the internal consistency of a test. This psychometric index evaluates whether different parts of a test are consistent with each other, providing an indicator of the instrument's stability over time.
Split-half reliability is determined by dividing the total set of items (e.g., questions) relating to a construct of interest into halves (e.g., odd-numbered and even-numbered questions) and comparing the results obtained from the two subsets of items thus created.

Split-half reliability requires only one test administration, so participants are unaware of any comparison. It is obtained by splitting the items into two equivalent sets and by correlating the pairs of scores (Pearson product-moment coefficient, r). Many kinds of split are possible, but some of them will not lead to equivalent sets.

Estimating the reliability of cognitive task datasets is commonly done via split-half methods. We review four methods that differ in how the trials are split into parts: a first-second half split, an odd-even trial split, a permutated split, and a Monte Carlo-based split. Additionally, each splitting method could be combined with stratification by task design. These methods are reviewed in ...

If we compute one split-half reliability and then randomly divide the items into another set of split halves and recompute, we can keep doing this until we have computed all possible split half estimates of reliability. Cronbach's Alpha is the geek equivalent to the average of all possible split-half estimates (although that's not how we do it.)
