by Marco Taboga, PhD. A random variable has a Chi-square distribution if it can be written as a sum of squares of independent standard normal variables. Sums of this kind are encountered very often in statistics, especially in the estimation of variance and in hypothesis testing.
The Chi-Square Test gives a way to help you decide if something is just random chance or not.
6 sty 2020 · The Chi-Square distribution table is a table that shows the critical values of the Chi-Square distribution. To use the Chi-Square distribution table, you only need to know two values: The degrees of freedom for the Chi-Square test. The alpha level for the test (common choices are 0.01, 0.05, and 0.10)
