Problems with NORMDIST
Should I be concerned that NORMDIST(4.92, 4.94, 0.08, FALSE) returns
4.83? This should be the noncumulative (density, mass) function
associated with the normal distribution. Surely it cannot exceed 1
because the entire area under the curve cannot exceed 1, by definition
of probability distribution. The related NORMSDIST problem:
NORMSDIST(-0.25, 0, 1, FALSE) returns 0.3866, which seems reasonable.
Can someone please reconcile the answers, or explain why Excel allows
probability distributions to have values greater than one?
Thank you.
