Line of Best Fit

Key Stage 3

A line of best fit is drawn on a Scatter Graph to fit the trend.

A line of best fit may be a straight line or a curve depending on how the points are arranged on the Scatter Graph.


This scatter graph shows a straight line of best fit.	This scatter graph of Extension against Weight results in a straight line of best fit.

This scatter graph of Image Distance against Object Distance of a Lens results in a curved line of best fit.	This scatter graph showing how temperature affects enzyme activity results in a curved line of best fit.
