Due to the COVID-19 pandemic, many colleges are offering different types of courses: Face to
Face, Hybrid, Synchronous Online, and Asynchronous Online. Researchers were interested in
determining if there is a difference in the overall course average for a Freshmen level College
Algebra course for these different types of courses. It is believed that a student's overall success in
previous courses could be a determining factor in how well they perform in the different types of
courses, thus the students were blocked based on GPA. The data is listed below.
