Normal Distribution in statistics

Normal distribution is a statistical distribution that occurs in many natural phenomena and measurements. It is also known as the Gaussian bell curve.

Characteristics of Normal Distribution:

• The distribution is symmetrical around the mean.
• The majority of the data is close to the mean, and the probability decreases with increasing distance from the mean.
• The shape of the distribution is determined by the mean and standard deviation.

Significance in Statistics:

Normal distribution is crucial as many statistical methods assume that the data is normally distributed. This allows the application of various statistical tests and simplifies result interpretation.

Graphical Representation

Normal distribution can be graphically represented by a bell curve.
