You plan to develop a regression model to further investigate how various factors influence students’

Result.

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.

(2 marks)

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).
