Abstract:
As a measure of mathematics anxiety, the Mathematics Anxiety Rating Scale (MARS) has been a major scale used for research and clinical studies since 1972. Despite the usefulness of the original scale, researchers have sought a shorter version of the scale partly to reduce the administration time of the original 98-item scale. This study created a shorter version of the MARS and provides reliability and validity information for the new version. The Cronbach alpha of .96 indicated high internal consistency, while the test-retest reliability for the MARS 30-item was .90 (p<.001). The validity data confirm that the MARS 30-item test is comparable to the original MARS 98-item scale.

Arithmetic Mean
When all the values in a data set are not unique, the sum in the numerator can be calculated by multiplying each distinct value by its frequency.
Sometimes, the arithmetic mean of a sample can be affected by a few data points that are...
Ratio Level of Measurement
A set of data measured using the ratio scale takes care of the ratio problem and provides complete information. Ratio scale data are like interval scale data, except they have a zero point and ratios can be calculated. For...
Anxiety: Overview
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

Geometric Mean
In cases of multiplicative data, the geometric mean is used for statistical analysis. First, the product of all the elements is taken. Then, if there are n elements in the...
