A basis for analyzing test-retest reliability.
Three sources of variation in experimental results for a test are distinguished: trials, persons, and items. Unreliability is defined only in terms of variation over trials. This definition leads to a more complet~ analysis than does the conventional one; Spearman’s contention is verified that the conventional approach--which was formulated by Yule--introduces unnecessary hypotheses.

Additional evidence for test-retest reliability is needed to optimize clinical decision making after concussion. OBJECTIVE To document test-retest re...
متن کاملTest-retest reliability of the Dynavision apparatus.
The Dynavision apparatus was developed to measure and train a number of psychomotor s u s , including visual scanning, peripheral visual awareness, and visuomotor reaction time (Performance Enterprises, 1992). Although several rehabilitation and human performance centers currently use the apparatus in occupational therapy and sport-related training, no reports of reliability have been published...
متن کاملTest-retest reliability of three Dynavision tasks.
The test-retest reliability of three Dynavision tasks of graded difficulty was estimated as high, with intraclass R correlation coefficients ranging from .88 to .97, and paired correlation coefficients ranging from .74 to .92. Recommendations are made for reliable testing procedures.
