The Normal Distribution

Family of Distributions with the same general shape (i.e., Gaussian distributions, bell curves) which feature a single peak at the precise center of the distribution, are symmetrically concentrated in the middle and decrease the further you go into the tails. They reflect a binomial distribution at very large sample sizes. Normal distributions are centered on the population mean (m) and dispersed around it with a given population variance (s2). A Standard Normal Distribution is one that has the following parameters (m=0, s2=1, g1=0, g2=0). Any general normal distribution can be converted to a Standard Normal Distribution (m=0, s2=1) using the Standard Normal Deviate () or z-Score.
