Against coefficient of variation for estimation of intraindividual variability with accuracy measures
Previous studies have shown that intraindividual variability (iV) in performance is an important indicator of individual’s cognitive functioning and neurological integrity. While most experiments have examined iV of performance using Reaction Time data (RTs), few studies have considered it with accuracy measures (e.g. number / percentage of correct responses). For these two types of measures, i...
متن کاملSample size planning for the coefficient of variation from the accuracy in parameter estimation approach.
The accuracy in parameter estimation approach to sample size planning is developed for the coefficient of variation, where the goal of the method is to obtain an accurate parameter estimate by achieving a sufficiently narrow confidence interval. The first method allows researchers to plan sample size so that the expected width of the confidence interval for the population coefficient of variati...
متن کاملAccuracy Measures for Neural Population Codes with Correlated Variability
Information theoretic measures such as the mutual information, and the recently proposed stimulus-specific information, provide a powerful tool for the study of the neural code. In practice, however, it is difficult to calculate these measures from experimental results due to the amount of data required. Fisher information, and derived quantities such as IFisher , are a popular alternative as t...
متن کاملIntraindividual Variability 1 Running head: INTRAINDIVIDUAL VARIABILITY Describing Intraindividual Variability at Multiple Time Scales Using Derivative Estimates
The study of intraindividual variability is central to the study of individuals in psychology. Previous research has related the variance observed in repeated measurements (time series) of individuals to trait–like measures that are logically related. The use of intraindividual measures such as intraindividual standard deviation or the coefficient of variation are likely to be incomplete repres...
متن کاملthe effects of time planning and task complexity on accuracy of narrative task performance
هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
