Book Publishers Survey Professors on Textbook Attitudes

The Association of American Publishers commissioned this study on the necessity of textbooks to teach college classes. It provided the sample of 16,000 e-mail addresses of professors of all subjects nationwide and the online survey received a 6% response rate. Margin of error is stated as 3.2% with subgroups having greater error. We question why the largest sample frame is among professors of education/human sciences and science/mathematics courses, whose textbooks likely carry the highest purchase prices.
