Figure 16. Four graphs showing the shape of distributions for risk analysis. On each, the y-axis is probability and the x-axis is cost or duration. The normal continuous distribution graph has a regular bell-shaped curve. The shape of the curve is right-skewed in the lognormal continuous distribution graph. The shape is triangular in the triangular continuous distribution graph. A bar graph is used to show declining cost or duration in discrete distributions, after an initial increase.
