Wikipedia
Analysis of variance
Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures (such as the "variation" among and between groups) used to analyze the differences among means. ANOVA was developed by the statistician Ronald Fisher. ANOVA is based on the law of total variance, where 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 two or more population means are equal, and therefore generalizes the t-test beyond two means. In other words, the ANOVA is used to test the difference between two or more means.

analysis of variance
Analysis of variance, also known as ANOVA, is a statistical method used to compare the means of three or more independent groups in order to determine if there is a significant difference among them. It analyzes the variability among group means, taking into account the amount of variation within each group and between different groups. ANOVA examines the impact of one or more factors by comparing the means of different samples, and it assumes that populations from which samples are derived are normally distributed and have equal variances.

Analysis of variance
Analysis of variance is a collection of statistical models used to analyze the differences between group means and their associated procedures. In 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 t-test to more than two groups. Doing multiple two-sample t-tests would result in an increased chance of committing a type I error. For this reason, ANOVAs are useful in comparing three or more means for statistical significance.
