[FONT="]Hi all, I have some summary statistics from a data set that look something like this:
Category------Color---------Avg Growth-------Std Error
Flowers--------Red-------------1.1--------------1.5
Flowers--------Blue------------2.4--------------1.5
Flowers--------Yellow----------5.1--------------1.4
Flowers--------All Colors-------2.9--------------0.8
What I would love to do is calculate/estimate the average growth and standard error of the combined set of Red and Yellow flowers. Ideally, I'd have access to the underlying dataset so I could calculate these measures directly, but I don't have access to the raw data.
Is there a way I can estimate the combined Avg Growth and Std Error of the Red and Yellow flowers?
Any advice is appreciated.
Thank you![/FONT]
