Normal Distributions and the Scientific Method

Learning outcomes

After working through this module you should be able to:

Outline the three steps that describe good scientific procedure.
Name the parameters that describe a normal distribution and explain how the distribution of a variable changes in response to changes of these parameters
Indicate where the middle 68%, 95% and 99% of a normal distribution lies relative to the mean of the distribution.
Indicate how the values of the mean and standard deviation of one normal distribution need to change in order to increase or decrease the overlap it has with a second normal distribution.
