title: [Comparing population means using the ANOVA method].
abstract: ANOVA is the abbreviation of the ANalysis Of Variance. It was developed for inferences concerning more than two populations. The tested hypothesis is the equality of the means of several normal populations. Some mathematical aspects are presented and also advantages and drawbacks of the method are marked out. Finally a practical example (implementing the ANOVA test) using the SPSS statistical software and also Microsoft Excel are shown.
