| A normal frequency distribution is a theoretical continuous, symmetrical, bell-shaped distribution function.
| | (OFT). |
| Its mean, mode and median are all the same; and both the tails of the bell curve are infinitely long.
| | An independent professional organisation, which plays a leading role in promoting and protecting consumer interests throughout the UK, while ensuring that businesses are fair and competitive. |
|
| |
|
| Because of its symmetry, a normal frequency distribution can be described fully by its mean and its standard deviation.
| |
|
| |
| Commonly abbreviated to ''normal distribution''.

|
| |
| Simple normal distributions are frequently used for modelling uncertainty. However, reality is rarely so neat and symmetrical as the normal distribution model.
| |
|
| |
| This can lead to spurious accuracy and a false sense of security from relying on models of that kind.
