Normal distribution in nature
WebThe normal distribution is symmetric about the mean. That is, the distributions of values to the right and left of the mean are mirror images. 68% of the values in the distribution fall within one standard deviation of the mean (to the left and right). 95% of values fall within two standard deviations, and 99.7% within three.
