The Spearman-Brown Formula strengths is that it can specify how reliable a test is based on the test being change order or reduced.

It also works in inverse cogent a researcher how many points needed to append in order to achieve a defined reliability constant.

Additionally, reliability test are higher for complete vs. half test formula postulations thus, with this instrument lengthy tests work best. Split-half The split-half form measures reliability by making two halves in the assonant test that are comparative in the same way as the bilateral forms.
