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
4. What does a Discriminant Functions Analysis (DFA) look to do?
- It aims to find a set of variables that create a statistically discriminant functionality
- 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
5. A venn diagram is created depicting the relationship between altruism (D.V) and Agreeableness (I.V) and Happiness (I.V). Happiness is the largest circle. What does this suggest?
- it correlates highly with Altruism and Agreeableness
- It has the largest level of residuals
- It has the largest variance
- It has the smallest variance
