    which statistical tests to use?




    Hi,

    I am very new to statistics. I have some data that I would like to perform additional statistical analysis on it.

    The data is related to two groups of people.
    Group 1: control group
    Group 2: people with obesity

    Group 2 is following a healthy food plan.
    Measurements are being made for each member in both groups, on 10 separate time points.
    Measurements for example include: weist, belly, neck, etc ...
    What I have done is that for each person, I have calculated the mean for every separate measurement.

    1- From this point onward, given the data I have, which statistical tests can I use to know the effectiveness of the food plan? i.e. the change in body measurements of Group 2 with respect to time?

    2- Also, which statistical tests can I use to have a better overview and comparison of Group 1 and Group 2 with respect to time?

    I just need some general headlines and some guidance, and I will dig myself into details.
    Many thanks in advance, your help is appreciated.

    Was the diet randomized?


    Do you have a baseline measure for each person?


    Perhaps repeated measures analysis controlling for baseline values of measurement.
