    Hello,
    This may be basic for most of you, but Im stuck. I need to get a weighted average for activities as they are completed by multiple groups.
    For example within one group we have 3 responders. The averages for one activity are 15%, 5%, 42%.
    Another couple in a different group perform the same task and average 18% and 20%
    One person from a third group does the activity and averages 32%
    I need to calculate the combined or weighted averages within each group and then across all groups.
    And I need to figure out how to calculate a tolerance. Our current confidence is 90%. Total population is 530 (dont hassel me about sample size; I lost that battle).
    Thank you very much for your help!
