Compare ANOVA and regression.
What will be an ideal response?
In ANOVA, the independent variable is nominal or ordinal but in regression, it is an interval-ratio variable. With ANOVA, we decomposed the total variation in the dependent variable into portions explained (SSB) and unexplained (SSW) by the independent variable. Next, we calculated the mean squares between and mean squares within. The statistical test, F, is the ratio of the mean squares between to the mean squares within. With regression analysis, we decomposed the total variation in the dependent variable into portions explained, regression sum of squares (SSR), and unexplained, residual sum of squares (SSE). The mean squares regression and the mean squares residual are calculated by dividing each sum of squares by its corresponding degrees of freedom.
