Quizplus · Accepted Answer

A normal distribution is defined by its mean (represented by the symbol μ) and its standard deviation (represented by the symbol σ). It is a bell-shaped curve that is symmetric around the mean, and is often used to model natural phenomena such as heights, weights, and test scores. The other choices do not involve both mean and standard deviation.
