We might say that standard deviation specifies the shape (flat, peaked) of the normal curve.
The mean, then, determines the location of the normal curve along the horizontal base line. Two
normal curves may have exactly the same standard deviation (and thus the same shape) but have
different means and thus be centered at different locations along the baseline. For example, let's
look at two curves which both have a standard deviation of 2 inches. Curve A has a mean of 56
inches and Curve B has a mean of 66 inches. The curves would appear as follows along the
same continuum or baseline:
How would you specify the shape and the location of a normal curve?
