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.
Recognize and use the standard normal probability distribution. A special continuous distribution, called normal, is the most common and therefore most important of all the distributions. It is widely used and even more widely abused. Its graph is bell-shaped. You see the bell curve in almost all disciplines.
The Normal distribution is also known as Gaussian or Gauss distribution. Many groups follow this type of pattern. That's why it's widely used in business, statistics, and in government bodies like the FDA: Heights of people. Measurement errors. Blood pressure. Points on a test.
