The Relationship of Reliability in Classroom Research to the Amount of Observation: An Extension of the Spearman-Brown Formula.
Rowley, Glenn
Journal of Educational Measurement, v15 n3 p165-80 Fall 1978, 78
The reliabilities of various observational measures were determined, and the influence of both the number and the length of the observation periods on reliability was examined, both separately and jointly. A single simplifying assumption leads to a variant of the Spearman-Brown formula, which may have wider application. (Author/CTM)
