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 ...

Normal distribution, also known as the Gaussian distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than ...
