#### More About the Chi-Square distribution

The Chi-Square distribution is one of the most fundamental distributions in Statistics, along with the normal distribution and the F distribution. Technically, the Chi-Square distribution is obtained by summing the square of variables that are independent and normally distributed

The Chi-Square distribution is one of the crucial continuous distributions in Statistics. You can use other probability calculators for continuous distributions, such as our normal probability calculator , F-distribution calculator or our uniform probability calculator , among many others.
