RM - Unit 110 - Linear equations
Book: Analysing Data Using Linear Models
Chapter 4: 4.1, 4.2
Chapter 4.1: Dependent and independent variables
The variable that measures the result is usually taken as the dependent variable/response variable. The
theoretical cause or antecedent is usually taken as the independent variable/predictor
variable/explanatory variable.
Chapter 4.2: Linear equations
Linear relationship - two variables are said to be linearly related if their relationship can be described by
a linear equation with an intercept and a slope.
Intercept - the value for Y (dependent variable) if X=0 (independent variable).
Slope - the change in Y when we increase X by 1 unit.
