A study involving 441 students enrolled in pre-calculus mathematics courses at Black Hawk College, Illinois, during Spring 1981 was conducted to measure the correlation between the level of students' math anxiety and four independent variables: sex, age, math background (as measured by the highest level of math course previously completed), and the last grade received in a mathematics course. The study involved: (1) the administration of the Mathematics Anxiety Rating Scale (MARS) to the students to measure their math anxiety on an increasing scale of 98 to 490; (2) the administration of a second instrument to determine the four independent variable characteristics; and (3) a statistical analysis of the data to determine those correlations that were significant at the .05 level. The study revealed that age was the only variable that was not statistically significant in the determination of the level of math anxiety. Females were significantly more likely to have higher levels of math anxiety than males. Students who had completed only a general mathematics course were more likely to have higher levels of math anxiety than students who had completed more difficult courses, and students receiving a "C" in their previous math courses were more likely to have higher levels of math anxiety than students who had received higher grades. The study report reviews relevant literature and details statistical findings. (JP)
