Analysis of variance (ANOVA) is a collection of statistical models used to analyze the differences among group means and their associated procedures (such as "variation" among and between groups), developed by statistician and evolutionary biologist Ronald Fisher.
In statistics, a confounding variable (also confounding factor, a confound, or confounder) is an extraneous variable in a statistical model that correlates (directly or inversely) with both the dependent variable and the independent variable.

A statistical hypothesis is a hypothesis that is testable on the basis of observing a process that is modeled via a set of random variables.
In statistics, statistical significance (or a statistically significant result) is attained when a ''p''-value is less than the significance level.
