Asymmetrical Distribution: Definition and Examples in Statistics

WebSymmetrical distribution is a statistical term that refers to a distribution of data that is mirror-image across a central value. The most common type of symmetrical distribution is the normal distribution, which is often represented by a bell curve. In a normal distribution, the mean, median, and mode are all equal. WebAn extremely common example of a symmetrical distribution is the normal distribution (bell-shaped curve). So the mean and median of a normal distribution are the same. Since a normal distribution is also symmetric about its highest peak, the mode (as well as the mean and median) are all equal in a normal distribution. Have a blessed, wonderful day!
