Viewing the best-fit line on a scatterplot

The best-fit line attempts to fit a straight line through all the points on a scatterplot, minimizing the sum of the squared distance between the line and the points. It is equivalent to a simple regression of the selected column (Y value) on the covariate (X value).

To view a best-fit line on a scatterplot:

  1. In the Summary view, click the Configure button below the scatterplot
  2. Choose the radio button labeled Always, Never, or Only if significant

The last option will display the best-fit line only if the correlation coefficient between the two columns is statistically significant.
