Reliability And Validity Of Michigan School Libraries For The 21st Century Measurement Benchmarks, Natosha Nicole Floyd
Wayne State University Dissertations
The purpose of this study was to examine the psychometric properties of the Michigan School Libraries for the 21st Century Measurement Benchmarks (SL21). The instrument consists of 19 items with three subscales: Building the 21st Century Learning Environment Subscale, Teaching for 21st Century Learning Subscale, and Leading the Way to 21st Century Learning Subscale. The sample consisted of 54 respondents who were administered the instrument in 2014 and 2015. Cronbach’s alpha for the total instrument was 0.807 (n = 19 items). Exploratory factor analysis (EFA) was used to measure construct validity. The findings derived from the EFA did not tend …
Objective Statistics For The Measurement Of Agreement, Elizabeth Perkin Moen
Objective Statistics For The Measurement Of Agreement, Elizabeth Perkin Moen
Wayne State University Dissertations
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 …
