Most English professors complain that students don’t write very well. In particular they point out that students often confuse quality and quantity. A study at the University of Texas examined this claim. In the study undergraduate students were asked to compare the cost benefits of Japanese and American cars. All wrote their analyses on computers. Unbeknownst to the students, the computers were rigged so that some students would have to type twice as many words to fill a single page. The number of words used by each student was recorded. Can we conclude that students write in such a way as to fill the allotted space?
