Part of the grant required conducting a study to determine if the addition of economics applications
would improve student attitudes about college algebra. Faculty designed a survey that would score
students 'attitudes with respect to college algebra on a scale of 1-10. Ten college algebra sections
(classes) were selected based on which faculty members responded first to an email request. Out of
these 10 sections, 5 instructors agreed to use the economics applications. The other five sections just
used the usual curriculum without the economics applications. It was found that the classes who had the
economics applications had a mean score of 6.5. Whereas the other group had a mean score of 6.
1. What is the research question being asked?
