    Unbalanced samples




    Hi!

    I want to compare between two sample, but they have non equivalent means between demographic parameters such as age and more.
    What do you recommend to do in-order to balance between the samples and make following tests like T-test and Chi-square.

    Thanks,
    Hadar.

    Re: Unbalanced samples


    So you want to compare two samples on some variables, but they differ on some other characteristics that may affect your analyses - is this correct.


    Following approaches can be used:


    -Match on troublesome variables;

    -Control for them in a regression model;


    -Use propensity scores (weights) to balance groups


    If you have multiple tests, I would imagine the middle option may be best.
