## normal distributionIn statistics, an ideal distribution which is symmetrical about its mean. It can be written in the form: where f(x) is the relative frequency, σ is the standard
deviation, μ is the mean, and π
and e have their usual values. Note that
in a normal distribution the mean, median,
and mode coincide. The characteristic bell-shaped
curve shown when f(x) is plotted against x is called
the normal curve. The distribution is also known as the
"Gaussian distribution" for Karl Gauss. ## Related category• PROBABILITY AND STATISTICS | |||||
