ANOVA (ANalysis Of VAriance) is a statistical technique commonly seen in radiology research.

ANOVA analyzes are conceptually similar to the student t-test, but involve comparison of multiple groups at once. The alternative to an ANOVA would be multiple head-to-head t-tests, but this would likely prove much more costly and time consuming, and the risk of encountering a type I error increases, the more studies are performed.

There are different types of ANOVA, useful in different situations

ANOVAs are generally performed with the appropriate computer software.
