ANOVA (Analysis of Variance) Test

A test used to measure the statistical difference of the mean (a.k.a. average) of a continuous (a.k.a. variable or numerical) value to two or more discrete (a.k.a. attribute or categorical) factors. It is generally used when the distribution for the continuous value is normal, hence the use of the mean. When the distribution is non-normal, the mean may not be valid so the median would be a better measure for central tendency; in those cases, try the Mood's Median Test or the Kruskal-Wallis Test.
