    Need help with paired t-test?

    Hello forum,

    It has been years since I took stats in college and I am having difficulty determining which test is most appropriate.

    Here is the situation.

    I have multiple locations that were sampled for population size before and after a treatment was applied. However, I have an uneven number of samples i.e. for site 1 I have 3 measurements before and 5 after, and for site 2 I have 5 before and 10 after, etc.

    My gut is telling me this is a paired t-test but I am not sure how to deal with the unequal sampling.

    Any help would be appreciated,

    Thanks J.

    p.s. I typically use sysstat and this is post-hoc, I know the design scheme isn't good.

    So you have multiple observations per person that are not even between sites or you have uneven number of people between sites?
