**bell**′ curve` n. a frequency distribution in **statistics** that resembles the outline of a **bell** when plotted on a graph. Also called **bell**-**shaped** curve.

The empirical rule - formula ∑ - sum x i - each individual value from your data n - the number of samples

**bell** curve. A symmetrical **bell**-**shaped** curve that represents the **distribution** of values, frequencies, or probabilities of a set of data. It slopes downward from a point in the middle corresponding to the mean value, or the maximum probability.

How to use excel to **create** a **bell** **curve**. Select the "Linear" option in the "Type" section, and type "0.25" into the "Step value" field. Type "4" into the "Stop value" field and press the "OK" button. The "Step value" is customisable. Enter a smaller number to generate a **curve** with greater detail and more points, such as "0.1". A higher number will show fewer data points.
