Answer 1

ANOVA is short for Analysis Of Variance.

Step-by-step explanation:

It is a statistical method whereby the variation in observations is divided into small different components. ANOVA provides a statistical test on the equality of two or more population means. A one-way ANOVA is used to analyse two or three groups of data so as to gain information about the relation of the independent and dependent variables.
