    Ordinal dependent variable and catagorical independent - which test




    Quick question for the Sages of the forum

    I have a study looking at patients who have been injured with a score attributed - ordinal data
    Each patient then might or might not undergo an operation - catagorical independent variable.

    I need a test to check the hypothesis the higher the injury score the more likely the patient had an operation

    Im just checking but I think the most appropriate test is a Chi Squared ?

    am I right ?

    Thanks in advance

    You could re-formulate your question and ask whether
    those patients with an operation had higher scores than
    those without, and perform a Mann-Whitney U-test.

    With kind regards
