The Normal Approximation to the Binomial Distribution
The process of using the normal curve to estimate the shape of the binomial distribution is known as normal approximation.

The Scope of the Normal Approximation
The scope of the normal approximation is dependent upon our sample size, becoming more accurate as the sample size grows.

Calculating a Normal Approximation
In this atom, we provide an example on how to compute a normal approximation for a binomial distribution.

Change of Scale
In order to consider a normal distribution or normal approximation, a standard scale or standard units is necessary.
