This applet allows users to drag sliders to change the mean and standard deviation of the normal distribution. The applet shows how changing these two values determines the shape and spread of the ...

Basically, this conversion forces the mean and stddev to be standardized to 0 and 1 respectively, which enables a standard defined set of Z-values (from the Normal Distribution Table) to be used ...

This basic example describes the probability and distribution of results. There are many types of distributions, one of which is the normal or bell curve distribution. In a normal distribution ...
