Normal Distribution

The Normal distribution is perhaps the most commonly used probability distribution A mathematical representation of the relative likelihood of a variable having certain specific values. It can be expressed as a PDF (or a PMF for discrete variables), CDF or CCDF.. It can be used, for example, to represent uncertainties resulting from unbiased measurement error, and (because of the central limit theorem) the value of a sum of other variables.

The Normal distribution is defined by a Mean and a Standard Deviation. GoldSim also allows you to truncate the distribution by checking the Truncated box and specifying a Minimum and a Maximum:
