Frick, Ted; Semmel, Melvyn I. – Review of Educational Research, 1978
Observer disagreement is important because it limits the reliabilities of observational measures. To avoid this limitation, observers should be trained, and criterion-related and intraobserver agreement measures should be used both before and during a study. Several agreement coefficients are examined for their applicability. (Author/BW)
