Multiple Linear Regression MLR – the model is a linear equation with at least two explanatory variables (independent) and one explained variable (dependent)

The relationship between examination mark, study time and intelligence: Examination mark =  Study time +  Intelligence Examination mark = 0.65 Study time + 0.30 Intelligence A student with an intelligence score of 110 who studies for 30 hours per week will obtain the following examination mark: Examination mark = (0.65 x 30) + (0.30 x 110) = 19.5 + 33 = 52.5 If the same student studies for 40 hours then: Examination mark = (0.65 x 40) + (0.30) x 110 = 26 + 33 = 59
