Chapter 14 – Normal Distribution
... There are an infinite number of normal distributions, one for each selection of mean and standard deviation. In this course, we study standard normal distribution, where a normal random variable has a mean of zero and a standard deviation of one. Normal distributions have a symmetrical, bell shaped ...

... One standard deviation away from the mean ( ) in either direction on the horizontal axis accounts for around 68 percent of the data. Two standard deviations away from the mean accounts for roughly 95 percent of the data with three standard deviations representing about 99.7 percent of the data. ...
