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!0December 10, 2009 at 9:34 pm #187470
