While a two-dimensional ogive or a cross-section of a three-dimensional ogive may represent the shape of a given distribution, they are only good for representing higher-likelihood (one- and two-sigma) outcomes because ogives do not have characteristic low-likelihood tails tails.
For very well managed processes (better than four sigma accuracy), a custom ogive may provide a very good approximation of resulting distribution.

I use a bar graph to represent my favorite pies, and a pie graph to represent my favorite bars.
standard deviation is best measure of dispersion because all the data distributions are nearer to the normal distribution.
