Normal curve features:
• Normal distributions are symmetric around their mean.
• The distribution has two parameters, mean (µ, mu) and standard deviation (σ, sigma)
• The mean, median, and mode of a normal distribution are equal.
• 68% of the area (data points) lies within one standard deviation (+/-1 sigma) of the mean.
• 95% of the area (data points) lies within two standard deviation (+/-2 sigma) of the mean.
• 99.7% of the area (data points) lies within three standard deviation (+/-3 sigma) of the mean.
