Contents
Key Stage 3
Meaning
A line of best fit is drawn on a Scatter Graph to fit the trend.
About Lines of Best Fit
- A line of best fit may be a straight line or a curve depending on how the points are arranged on the Scatter Graph.
Examples
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. |
Key Stage 4
Meaning
A line of best fit is drawn on a Scatter Graph to fit the trend.
About Lines of Best Fit
- A line of best fit may be a straight line or a curve depending on how the points are arranged on the Scatter Graph.
Examples
This scatter graph shows a positive correlation and a straight line of best fit with variables are proportional. | This scatter graph of Extension against Weight results in a straight line of best fit that crosses through zero showing the weight and extension are directly proportional. |
This scatter graph of Image Distance against Object Distance of a Lens results in a curved line of best fit with a negative correlation that is inversely proportional. | This scatter graph showing how temperature affects enzyme activity results in a curved line of best fit. |
