The problem that exists when using one or more readability indexes to ascertain a text grade level is the varied outcomes received on any given text from readability indexes that purport to measure the same construct. This study aims to provide practitioners with data to make informed decisions regarding interchangeability of readability indexes. A total of n = 244 narrative (n = 116) and expository texts (n = 128) passages from grades 1-5 were evaluated using the following readability indexes: Flesch-Kincaid Grade Level, Fry Graph, Spache, Dale-Chall, Gunning Fog, and Smog. Fifteen (15) comparison sets were analyzed using Bland-Altman method …

Objective Statistics For The Measurement Of Agreement, Elizabeth Perkin Moen

The prevailing method for biomedical device interchangeability is a scatterplot of means and differences bounded by levels of agreement (Bland-Altman Plot) which results in subjective judgments made in the discernment of differences in data distribution and fit. The purpose of this study was to test four statistics - the Kolmogorov-Smirnov test, and three fit indices (NFI, GFI, & CFI) in order to identify a more objective statistic for device interchangeability. The Kolmogorov-Smirnov test proved incompatible with the data structure. The Normed Fit Index (NFI) proved most sensitive to correlation shifts where the Goodness of Fit Index (GFI) and Comparative Fit …
