Brown is based on his doctoral dissertationwhich was already available at the time of publication. Reliability Analysis - Duration: The development and validation of a Portuguese version of the Motivated Strategies for Learning Questionnaire. Introduction to Measurement Theory. That is. Split-half tau-equivalent reliability is a reliability coefficient that can be used when the variances of split-halves are not equal. Psychometrika, 18 1
Until the developement of tau-equivalent reliability, split-half reliability using the Spearman-Brown formula was the. The Spearman-Brown Prediction Formula, also known as the Spearman-Brown Prophecy Formula or Correction, is a method used in evaluating test reliability. The most commonly used index of test score reliability is coefficient alpha. To adjust for this, psychometricians use the.
SB_SPLIT(R1, s) = split half coefficient (after Spearman-Brown correction) for. Product Moment Correlation formula be used to determine split-half reliability of.
However, because there are more parameters that need to be estimated than the given pieces of information, another assumption is needed. The systematic formula  is as follows.

|Spearman's rank correlation coefficient - Duration: Fast - Josh Kaufman - Duration: Can we defend a low or undesired level of reliability coefficient by estimating the ideal number of test items on the Spearman-Brown prophecy formula?
No, we cannot defend a low reliability in that way. Research By Designviews. The Spearman—Brown prediction formulaalso known as the Spearman—Brown prophecy formulais a formula relating psychometric reliability to test length and used by psychometricians to predict the reliability of a test after changing the test length.
