chi-square distribution
Definition
- The chi-square distribution is a distribution that results from the sums of squared standard normal variables. Even though the sums of normally distributed variables have a NORMAL DISTRIBUTION (with the shape of a BELL-SHAPED curve), the sums of their squares do not.
