Chi square test is the goodness of fit test to compare the values between the theoretical expected distribution and the distribution of the observed or categorical data. Chi square can only be used on numbers and not on percentages, ratios etc. Chi square test calculator helps us to find the chi-square value of comparison between the given data frequencies of the distribution.
Example 1: Calculate the chi-square statistic value of a distribution if the observed frequency is 6 and the expected frequency is 10.
Example 2: A surprise bag contains certain number of candies of two colors. Calculate the chi-square value for the following data:
