Publisher's Synopsis
Excerpt from Errors of Measurement and Correlation
I am indebted chie?y to Dr. Edward L. Thorndike, who has sponsored this study, for advice, encouragement, and inspiration. Dr. Henry E. Garrett, Dr. Henry A. Ruger, and Dr. Helen M. Walker have contributed invaluable advice during the progress of the investigation. I am indebted to Mr. Jack W. Dunlap, Dr. Laura H. V. Kennon, Dr. Irving Lorge, and Dr. Ella Woodyard for reading the manuscript and offering many helpful suggestions.
My interest in the problems discussed is due mainly to Dr. Truman L. Kelley of Harvard University. The pioneer work of Professor C. Spearman of the University of London has laid the foundations for all subsequent investigations in correlational psychology.
