    Which Statistical test Should I Use?

    I don't know what test to use to see if there is a relationship between two sets of data when they rely on each other.

    Example:

    # of people who slipped on wet floor: day 1 - 7. Day 2 - 8. Day 3 - 7.
    # of people who slipped on dry floor: day 1 - 3. Day 2 - 2. Day 3 - 3. . .
    Basically the number of people is always 10. I don't think I can do a chi square test because if one number changes, then so does the other. Is there a specific test for this situation?

    What do you mean by this?

    Have you seen the Wilcoxon signed rank test?

    Look here for an example,

    Wilcoxon signed-rank test - Wikipedia, the free encyclopedia

    give it a test drive with your data!

    I don't know if I'm right about this, but I don't think I can do a chi square test because the variables have to add up to ten (if one is 7 then the other has to be 3). I thought that this was the reason that you can't use percentages in a chi square test.
