THE HISTORY OF EDUCATIONAL RESEARCH discloses many quantitative studies of the content of textbooks, errors in grammar and spelling, analyses of technical and nontechnical vocabularies, the mathematics used in everyday life, and the like. This general area of research was summarized, with illustrations, by Good, Barr, and Scates (133). They recognized textbook analyses, analyses of large bodies of literature, activity analyses, vocabulary analyses, error studies, and analyses of record and report forms. To these we should probably add the quantitative analysis of motion pictures.
