Method	Description
Integral ( UnaryFunction f, double a, double b ) : double	Approximation of a definite integral of a unary function using Simpson's 3/8 rule.
ProbabilityLessThanX ( double x ) : double	The probability of getting x or less given a standard normal distribution.
ProbabilityLessThanX ( double x, double mean, double sd ) : double	The probability of getting x or less given a non-standard normal distribution.
StandardDeviation ( IEnumerable values ) : double	Calculate the standard deviation of a set of doubles.
StandardDeviation ( IEnumerable values ) : double	Caculates the standard deviation of a set of integer values.
StandardNormalPdf ( double x ) : double	The probability density function of the standard normal pdf.
Z ( double score, double average, double standardDeviation ) : double	Calculate the normal score of a raw score given the mean and standard deviation.
