The calculation takes three steps allowing you to see how the chi-square statistic is calculated. Chi Square Calculator for 2x2. This simple chi-square calculator tests for association between two categorical variables - for example sex males and females and smoking habit smoker and non-smoker.
Observations must be independent of each other so for example no matched pairs Cell count must be 5 or above for each cell in a 2 x 2. The results are in. And the groups have different numbers.
But is that just random chance. Or have you found something significant. Chi-Square Test of Independence Calculator.
A Chi-Square Test of Independence is used to determine whether or not there is a significant association between two categorical variables. To perform a Chi-Square Test of Independence simply fill in the cells below for a contingency table of up to 5 rows and 5 columns. Chi-squared χ 2 Test is a technique used in probability statistics to check if the results of χ²-distribution is statistically significant under null hypothesis.
