2. Characteristics of a Normal Distribution

4. • About 68% of values drawn from
a normal distribution are within
one standard deviation σ away
from the mean.
• About 95% of the values lie
within two standard deviations
• About 99.7% are within three
standard deviations.
• This fact is known as the 68-95-
99.7 (empirical) rule, or the 3-
sigma rule.
