To explain: About a
A normal distribution is referred to as normal as most of the data values within normal distribution are within a certain range of mean. So it is referred to as “normal”
Given:
A question “Why is a normal distribution normal?”
Explanation:
The data values in a normal distribution are very small when compared relatively to mean as most of the data points are within a small range of the mean. According to empirical rule of normal distribution, about 68% of data lie within 1 standard deviation of the mean and about 95% of data lie within two standard deviations of the mean and about 99.7% of data lie within three standard deviations of the mean. Thus data being within a small range from mean on either side it creates a bell shaped curve and it is referred as normal.
