Chi square value

The chi-square value is the value at the base line of the chi-square distribution.


Four distributions are very commonly used in statistics: the normal distribution, the t distribution, the chi-squared distribution and the F distribution. Depending on the test, a z, a t, a chi-square or an F is calculated.

The calculated chi square value is compared with the critical chi square value of the chi square distribution. If the calculated value exceeds the critical value, the result is called statistically significant.

The critical Chi square values can be found in tables. These tables can be found in any good statistical textbook or can be downloaded from our site.
