**How do you do a chi square test for independence?**

### What is a chi square test used for in SPSS?

**What is the null hypothesis in a chi-square test of independence?**

### How do you know if two variables are independent?

If X and Y are two random variables and the distribution of X is not influenced by the values taken by Y, and vice versa, the two random variables are said to be independent. Mathematically, two discrete random variables are said to be independent if: P(X=x, Y=y) = P(X=x) P(Y=y), for all x,y.
