What are the key characteristics of a Normal Distribution?
- The normal distribution is the one most frequently used by various professionals
- Several statistical analysis make an assumption that the data are following a normal distribution.
- According to the central limit theorem, the averages of measurements of individual data follow a normal distribution even if the individual data are from a difference distribution.
- Since the distribution is in the shape of a bell, it is often referred to as a bell curve.
