Typical Distribution - Essay Example For a gathering of measurements to be solid, they have to have an ordinary or chime formed bend. So as to help accomplish this result, the mean should be as near the middle as could be expected under the circumstances. Likewise, the standard deviation will probably be little so as to enable the bend to stay tall and limited.
