A Bell Curve is a perfectly normal distribution. Perfectly symmetrical. Otherwises it's not a Bell Curve.


Yes, but as I said, no real data is ever a perfect bell curve. When people say "it's a bell curve", they actually mean "it's reasonably well described by a bell curve".

Edit:

In fact, as the curve is truncated at zero, it can't be a perfect bell curve in any case, as one of the properties of the normal distribution is that the probability never reaches zero.

That the 1000 Novices aren't a random sample of the population? fionwe1987 - 29/10/2012 08:23:47 PM 666 Views
