Answer 2

The normal distribution refers to continuous variables as a continuous probability density function. It is used as a first approximation to describe random real value variables that tend to be grouped around an average value.

The normal distribution is followed either accurately or with a close approximation by most continuous phenomena.

Many discontinuous probability distributions can be accessed through the normal distribution. For example, many population characteristics, such as height, weight, scoring in a competition, etc.
