A Normal Distribution function () represents a normal distribution with a bell-shaped (Gaussian) curve. It supports the following statistical functions related to a normal distribution: density function, cumulative distribution function, quantile function, and randomly generated function. The default Function name is nd1.

Enter a Mean (default: 0) and Standard deviation (default: 1) of the normal distribution.

Here you can, if desired, edit the names of the variables for the cumulative function and the quantile function in the Cumulative function name field (default: nd1_cum) and Quantile function name field (default: nd1_cum_inv), respectively. The quantile function or inverse cumulative distribution function specifies the value of the random variable such that the probability of the variable being less than or equal to that value equals the given probability.

If desired, edit the name of the random function in the Random function name field (default: rn_nd1).

Enter the desired number of arguments for the normal function in the Number of arguments field (default: 1).

If you want to use a random seed, select the Use random seed check box. Then, from the Random seed type list, choose Fixed (the default) or Current computer time. Using Current computer time provides an indeterministic output from the random function, so that a different result is output each time. If you chose Fixed, then enter a value for the seed in the Random seed field.
