    Mean Ranks




    Hi all,

    Can someone help me to understand what mean rank scores actually mean once you've completed a mann-whitney test or wallis test?

    For example, if I coded my study for 1=strongly disagree, 2=disagree, 3= slightly disagree, 4=slightly agree, 5=agree, 6=strongly agree.

    If men had a higher score than women, could I say that men were more likely to agree than women?

    Or what statements can I actually make with mean rank scores?

    Any help is appreciated.

    T

    Given your data some may ague if it is ordinal or categorical. Regardless of this debate, I would say that median ranks may be more appropriate since a mean value of, say, 2.45 does not confer a alot of information.

    hi,
    I think the safe thing to say would be that men tend to have higher scores, which is not that much. E.g. it could happen that most women have a score of 1 while most men have a score of 2, so nobody agrees but men are less strongly opposed (or tend to be rated as such).
    As a side point I would miss the neutral option from the middle in this scoring - after 3 I would have 4 -"I do not care" and then the three remaining options .
