What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatterplot, showing the overall direction of the data.

How can you determine the strength of a trend in a scatterplot?

Back

The strength of a trend can be determined by how closely the data points cluster around the line of best fit. A strong trend has points that are close to the line, while a weak trend has points that are more spread out.
