    "independent of" vs "mutually exclusive"




    Hi,

    I am a stats newbie. Sorry about asking this trivial question.

    Say I have a 2 x2 contingency table. The categories defining rows and columns are marital status(single, married) and gender (male, female), respectively. I am wondering if the following questions from the same problem set mean the same thing.

    1. Are gender and marital status mutually exclusive?
    2. Is marital status independent of gender?

    Thanks,
    KC

    No.

    1. Are gender and marital status mutually exclusive?
    Mutually exclusive means 2 things can't happen at the same time. Like being honest and a politician.

    2. Is marital status independent of gender?
    This means one doesn't have a relationship with one another (little to no correlation). So being hockey player and having a lot of missing teeth are not independent of each other. Where as being a teacher and the need to go grocery shopping are pretty unreleated (independent) to one another.

    Trinker,

    I really liked what you put there

    “being honest and a politician are mutually exclusive”
