ANOVA is used to determine if there is a significant difference between two or more treatment groups. In two way ANOVA we can test two factors at once at check whether there is any difference between the various levels of the two factors. In engineering if the data corresponds to a situation where there are two factors observed, each factor has a various levels and each level of treatment is applied to a certain number of units, a two way ANOVA can be used to analyse the data.
