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

It also works in inverse cogent a researcher how many points needed to append in order to achieve a defined reliability constant. The weakness of the Spearman-Brown radiation pattern is that it is only effectual with consi stent test items that are include travail an! d duration. That is, only items that are the same. Additionally, reliability test are higher for complete vs. half test formula postulations thus, with this instrument lengthy tests work best.
