Abstract:
Psychometric properties of mathematics anxiety measures have not adequately been studied. Using a large sample size (N = 1,239), the authors developed an abbreviated math anxiety measure, examined its psychometric properties, and assessed the generalizability of the model across samples. Exploratory factor analysis yielded a nine-item measure and strong internal consistency, test-retest reliability, and good convergent/divergent validity was demonstrated with an independent sample. When administered to a replication sample, indexes suggested an excellent model fit. TheAbbreviated Math Anxiety Scale (AMAS) may represent a more parsimonious and valid approach to assess mathematics anxiety.

Mean Absolute Deviation
Let us consider a dataset containing the number of unsold cupcakes in five shops: 10, 15, 8, 7, and 10. Initially, calculate the sample mean. Then calculate the deviation, or the difference, between each data value and the mean. Next, the absolute values of these deviations are added and divided by the sample size to...
