Webb26 mars 2024 · The range is a measure of variability because it indicates the size of the interval over which the data points are distributed. A smaller range indicates less variability (less dispersion) among the data, whereas a larger range indicates the opposite. Webb16 nov. 2024 · However, before we perform multiple linear regression, we must first make sure that five assumptions are met: 1. Linear relationship: There exists a linear relationship between each predictor variable and the response variable. 2. No Multicollinearity: None of the predictor variables are highly correlated with each other.
