Normal population distribution curve
The normal distribution is the only distribution whose cumulants beyond the first two (i.e., other than the mean and variance) are zero. It is also the continuous distribution with the maximum entropy for a specified mean and variance. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other.

WebThe blue curve is a Normal Distribution. The yellow histogram shows some data that follows it closely, but not perfectly (which is usual). It is often called a "Bell Curve" … WebStep-by-step explanation. 1. The normal distribution is a continuous probability distribution that is symmetric around the mean, with most of the data falling within a few standard deviations of the mean. It is often used to model natural phenomena such as measurements of height, weight, or test scores.
