♥️ What Is Normal Distribution Used For

A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. 7.6: Normal Approximation to the Binomial. In the section on the history of the normal distribution, we saw that the normal distribution can be used to approximate the binomial distribution. Every normal distribution is a version of the standard normal distribution that's been stretched or squeezed and moved horizontally right or left. The mean determines where the curve is centered. Increasing the mean moves the curve right, while decreasing it moves the curve left. The standard deviation stretches or squeezes the curve. iGYcM9.
