This is part of the HSC Mathematics Advanced course under the topic Statistical Analysis: Bivariate data analysis.
Here we will learn to model a linear relationship by fitting an appropriate line of best fit to a scatterplot and using it to describe and quantify associations.
- Fit a line of best fit to the data by eye and using technology
- Fit a least-squares regression line to the data using technology
- Interpret the intercept and gradient of the fitted line
