Statistical Method in Educational Measurement

'Statistical Method in Educational Measurement' is a comprehensive guide designed to equip educators and researchers with the essential tools for interpreting and analyzing pedagogical data. Written by Arthur Sinton Otis, a prominent figure in the development of intelligence testing, this work bridges the gap between complex mathematical theory and practical application in the classroom and school administration.The text explores fundamental concepts such as the distribution of scores, measures of central tendency, and the calculation of variability. It provides detailed instruction on the use of correlation coefficients and the construction of percentile curves, which are crucial for evaluating student performance and the efficacy of educational programs. Otis emphasizes the importance of accuracy and scientific rigor in mental and educational measurements, offering clear explanations of how to handle raw data to derive meaningful insights.This work serves as a foundational resource for understanding the evolution of psychometrics and the quantitative approach to education. It remains a significant historical reference for those interested in the history of standardized testing and the development of modern educational assessment techniques.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
