Quizplus · Accepted Answer

Charles Spearman is best known for his work on factor analysis, which involves identifying underlying factors or dimensions that explain patterns of correlations among a set of variables. This would be the most likely topic of a book by Spearman, especially given that factor analysis has important applications in both mathematics and psychology. The other choices are less directly related to Spearman's work or interests.
