Chi square test is a statistical test conducted to compare data obtained through observation with data we would expect to obtain from a specific hypothesis.

 

In other words chi-square test is a test with test statistic that has a chi-square distribution when the null hypothesis is true, or any in which the probability distribution of the test statistic (assuming the null hypothesis is true) can be made to approximate a chi-square distribution as closely as desired by making the sample size large enough.

 

Chi square table is used in Chi square test to check if there is significant difference from the null hypothesis or weather the results support the null hypothesis.
