## Definition of the noun anova

What does anova mean as a name of something?

noun

1. a statistical method for making simultaneous comparisons between two or more means; a statistical method that yields values that can be tested to determine whether a significant relation exists between variables

## Explanation

1. ANOVA a.k.a. Analysis of variance is a collection of statistical models used to analyze the differences between group means and their associated procedures, developed by R.A. Fisher. In the ANOVA setting, the observed variance in a particular variable is partitioned into components attributable to different sources of variation. In its simplest form, ANOVA provides a statistical test of whether or not the means of several groups are equal, and therefore generalizes the t-test to more than two groups. As doing multiple two-sample t-tests would result in an increased chance of committing a statistical type I error, ANOVAs are useful in comparing three or more means for statistical significance.
2. Anova a.k.a. neuro-oncological ventral antigen 2 is a gene.
• also known as neuro-oncological ventral antigen 3, NOVA2 [amino acids 1-28]
