The Mathematical Anxiety Rating Scale (MARS) measures an 
individuals level of mathematical anxiety on a scale from 25 (no anxiety) 
to 100 (highest anxiety). A group of researcher administered the MARS 
to 50 students. One of the objectives of the study was to determine if there 
is a difference between levels of mathematical anxiety experienced by 
male and female psychology students.
