About the author
Born in Whitehall, Michigan, Truman Lee Kelley was an American psychologist, statistician, and psychometrician whose career bridged mathematics, education, and psychology. Reliable reference sources describe him as an important early figure in applying statistical methods to psychological research, especially in the study of testing and measurement.
Kelley is best remembered for advancing psychometrics and educational measurement at a time when those fields were still taking shape. He wrote influential books including Educational Guidance and Interpretation of Educational Measurements, and his work also contributed to factor analysis and classical test theory. His research helped make quantitative methods more central to psychology and the social sciences.
He died in 1961, but his name still appears in histories of statistics, testing, and psychological measurement. For listeners interested in the roots of modern assessment and data-driven research, he stands out as one of the scholars who helped build that foundation.
