business and finance bankruptcy# Why is a normal distribution curve bell shaped?

Last Updated: 28th June, 2020

**normal distribution**the mean, median and mode will be the same value, visually represented by the peak of the

**curve**. The

**normal distribution**is often called the

**bell curve**because the graph of its

**probability**density looks

**like**a

**bell**.

Accordingly, are all bell shaped curves normal distributions?

**All normal distributions** are symmetric and have **bell**-**shaped** density **curves** with a single peak. To speak specifically of any **normal distribution**, two quantities have to be specified: the mean , where the peak of the density occurs, and the standard deviation , which indicates the spread or girth of the **bell curve**.

Secondly, what does a normal distribution curve show? **normal distribution curve**. In statistics, the theoretical **curve** that **shows** how often an experiment will produce a particular result. The **curve** is symmetrical and bell shaped, showing that trials will usually give a result near **the average**, but will occasionally deviate by large amounts.

Also to know is, what does a bell shaped curve mean?

**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.

Is Bell Curve still relevant?

The **Bell Curve** system of performance appraisal intimidates HR managers as much as employees. For a long time, this forced ranking system has remained a topic of debate, but companies **still** continue to use it.
