please answer:
regression analysis
(a) Before you conduct any regression analysis, you use Excel to construct a correlation matrix of all the quantitative variables in the dataset.
Based on the correlation matrix, comment briefly on the linear associations between Result and other quantitative variables (viz. Age, Lectures and Tutorials) and whether these variables are a predictor of result.
(b) Conduct a simple regression on: (i) Age is a predictor of Result? (ii) Lectures is a predictor of Result? (iii) Tutorials is a predictor of Result?
Does this support your answers to Task 2 (a)?
(c) So that the categorical variables Gender, Medu and Relationship can be used in the regression, please show appropriate dummy variables. Note that we use one less dummy than the number of categories for any categorical variable.
