Mode

See also: Median, Mean, Statistical descriptions of model outputs, Presenting results introduction

The mode is the output value that is most likely to occur.

For a discrete output, this is the value with the greatest observed frequency:

For a continuous distribution output, the mode is determined by the point at which the gradient of the cumulative distribution of the model output generated values is at its maximum:

The estimate of the mode is quite imprecise if a risk analysis output is continuous or if it is discrete and the two (or more) most likely values have similar probabilities.

In fact the mode is of no practical value in the assessment of most risk analysis results and since it is difficult to determine precisely, it should generally be ignored.
