Definition of Normal Distribution

Definition of Normal Distribution

A normal distribution is a common way for continuous data to be distributed.

The normal distribution is a "bell curve" like the one in the picture.

Even if data doesn't exactly follow the normal distribution, the normal distribution can often be used to approximate the data.

A number of different types of data follow a normal distribution:

  • The heights and weights of people.
  • Measurement errors.
  • The lengths of lizards.
  • The widths of planks produced by a machine.

You will often hear teachers talking about "curving" the results of a test. By this, they mean that they will change the test marks so that they follow a normal distribution.
