1. ## Standard Deviation Graph

I have the following information about a test:
The lowest score is 0 and the highest score is 100
The standard deviation is 12.8
The average score is 72.2

I have the results of one of the tests where the person scored a 52.
How do I make a graph showing this information and how it relates to the individual's score?

2. ## Re: Standard Deviation Graph

sketch a bell curve centered at 72.2

At 72.2 the curve should be approximately 0.4
At 72.2 +/- 12.8 both sides should be approximately 0.25
Both sides should be nearly zero at 72 +/- 2 x 12.8

I guess then draw a line at 52 from the x axis to the curve.
