You plan to develop a regression model to further investigate how various factors influence students’
3. 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 on the linear
associations between Result and other quantitative variables (viz. Age, Medu, Lectures and
Tutorials) and whether these variables could be used as a predictor of result.
4. Based on the correlation matrix obtained in Question 3, would you say that:
(i) Age is a predictor of Result?
(ii) MEdu is a predictor of Result?
(iii) Lectures is a predictor of Result?
(iv) Tutorials is a predictor of Result?
Conduct simple regression to support your answers to questions (i) to (iv).
