Data Distributions Made Easy
Look at the website listed below and examine at least four situations in which the mean of the distribution was changed.
Normal Density Plotter
Answer these questions:
|What effect was produced in the shape of the distribution when the
standard deviation was increased?|
|What effect was produced in the shape of the distribution when the standard deviation was decreased?|
If you wish a bit more information, look at this example of "balls and pins" that demonstrates how samples of random events may tend toward normal distributions.
