2. In order to work out the f-ratio for a regression, we need MSm and MSr. How do we work out MSm?

MSm = dfm/SSr (Degree's of Freedom Model/ Residual Sum of Squares) Remember, the degree's of freedom for the model are the amount of variables in the model.

MSm = SSm/dfm (Model Sum of Squares / Degree's of Freedom Model) Remember, dam is simply the number of variables in the model.

MSm = dfm/MSm (Degree's of Freedom Model/ Model Mean Squares) Remember, model mean squares is the amount of variables in the model.

MSm = SSr/dfr (Residual Sum of Squares / Residual Degree's of Freedom) Remember, residual degrees of freedom is the amount of variables in the model.

3. Why do we use basic ratios?

To simplify the calculation of Sum of Squares

To simplify the calculation of F-Critical

To help an ANOVA partition

To calculate figures for the F-table

It aims to find a set of variables that give a direction of the main effect

It aims to find a set of variables that predict membership of groups

It aims to find a set of variables that are hidden outliers in the analysis
