This is the bell shaped curve of the standard normal distribution.
Calculates the probability density function area and lower and upper cumulative distribution functions of the normal distribution. 2 mean sd 2 mean sd. If data set have small standard deviation the data points are very close to the mean. Standard deviation may be abbreviated sd and is most commonly.
