PROPERTRIES OF A NORMAL DISTRIBUTION
MY 3
A normal distribution is continuous, symmetric, bell-shaped distribution of a variable. The known characteristics of the normal curve make it possible to estimate the probability of occurrence of any value of a normally distributed variable. The properties of the normal distribution are as follows:
1) The distribution is bell-shaped
2001
2) The mean, median, and mode are equal and are located at the center of the distribution
3) The normal distribution is unimodal
4) The normal distribution curve is symmetric about the mean
5) The normal distribution is continuous
6) The normal curve is asymptotic
7) The total area under normal distribution curve is 1.00 or 100%
