xkcd_ConfidenceIntervals.png

A single-panel comic. The comic is captioned ''Science Tip: If your model is bad enough, the confidence interval will fall outside the printable area.'' The cartoon shows a graph titled ''Fig. 2: Predicted Curve.'' The figure shows the curve in black. However, outside of the figure, the confidence interval is shown with a dashed grey line. The implication is that people looking at the figure would not see the confidence interval because it is outside of the figure's axis.
