Hint: PCA/EFA are not "research design/question"-based in the sense of estimation, so these questions are likely to be multilevel models and path analysis. You probably know more than you think you do. - e.g. start with an outcome variable. - ask yourself: "what in my question is asking about 'effects on Y'/'influences on Y'/'predicts Y'". </small> ] --- # Exam Strategy: Section B .pull-left[ **Section B - 85 MARKS** + 10 Questions + Marks range from 4 to 20 marks per question

These are going to be our main functions we have seen throughout DAPR3: `lmer()`, `principal()`, `sem()`, `fa()` print an output from the lab/lectures and annotate it. what does each bit of the output represent? </small> ] --- class: center, middle, animated, rotateInDownLeft # Questions --- # Mock Questions _(switch to pdf)_ --- class: center, inverse, middle, animated, rotateInDownLeft # End
