The independent variable is Sexual orientation which has 4 possible selections (0,1,3,4) and the dependent is the shopping category which has 2 possible selections (0 or 1).

What is want to compare is if 0 and 1 from the independent variable have any statistically significant difference as to their selection of 0 and 1's for the dependent variable and if 3 and 4 from the independent variable have any statistically significant difference as to their selection of 0 and 1's for the dependent variable.

For the dependent variable 1 stands for selected and 0 stands for not selected I want to know if there is any statistical significance among the two groups of the independent variables selections mentioned above.
