A study was designed to investigate the effects of two variables – (1) a student’s level of mathematical anxiety and (2) teaching method – on a student’s achievement in a mathematics course. Students who had a low level of mathematical anxiety were taught using the traditional expository method. These students obtained a mean score of 380 with a standard deviation of 20 on a standardized test. Assuming a bell-shaped distribution, where would approximately 95% of the students score?
