 Figure Out My Chi-Square Test (Test the significance of the relationship between two variables) This calculator will perform a 2 X 2 chi-square test.  This is a simple but very useful way to decide if two variables with two levels each are related to each other.    For instance, suppose you asked 100 men and 100 women whether they voted Democrat or Republican in the last election.  You find that 52/100 men voted Democrat and 60/100 women voted Democrat.  It looks as if women are more likely to have voted Democrat -- but is the difference strong enough to be reliable?  In other words, if you were able to sample everyone who voted, would you expect to still find that a higher percentage of women had voted Democrat?  This calculator will tell you. For our example, looking at political party by gender, you would make the entries shown below.  Your first variable is "gender" with two levels, "male" and "female".  Your second variable is "political party" with Democrat and Repuplican.  Now click "NEXT" at the bottom of the page and enter your own data.
