Normal Distribution Examples, Formulas, & Uses

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. 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. green bay bears line

WebWhen looking at normal distribution, the notation can be written as: X ~ N ( μ, σ 2) μ = the mean σ 2 = the population variance.
