This is a easy chi-square calculator for a contingency table that has up to five rows and five columns for alternative chi-square calculators see the column to your right. Statistic-parameter standard deviation of the statistic. Calculation for the Chi-Square test. Simply enter the Chi-Square statistic you obtained and the degrees of freedom. The Chi square test should be run when you want to test how likely it is that an observed distribution is motivated by chance. The null assumption is that the probability to switch from A to B equals the probability to switch from B to A equals 05.
The test uses Chi-square distribution.
Type in the values from the observed and expected sets separated by commas for example 2458112.
