By the end of this unit, students will be able to:
- understand the concept of a line of best fit and its role in representing data trends;
- create a line of best fit for a given data set using appropriate techniques;
- interpret the line of best fit and make predictions based on it.
Curriculum Alignment: Key Stage 4: Statistics
- Use and interpret scatter graphs of bivariate data; recognise correlation and know that it does not indicate causation; draw estimated lines of best fit; make predictions; interpolate and extrapolate apparent trends whilst knowing the dangers of so doing.
