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

ScatterGraphStraight.png
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.
ScatterGraphCurve.png
ScatterGraphCurve2.png
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

ProportionalGraph.png
ScatterGraphStraight.png
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.
ScatterGraphCurve.png
ScatterGraphCurve2.png
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.
