The ANOVA (Analysis of Variance) checks whether there are statistically significant differences between more than two groups. For this purpose, the mean values and variances of the respective groups are compared with one another. In contrast to the t-test, which compares two groups, the analysis of variance compares more than two groups. This Video is about the One-way ANOVA without repeated measurements also called one factorial Analysis of Variance without repeated measurements
