Betreff: st: graphing means with std dev
I would like to generate a graph that plots the mean age with whiskers
representing the standard deviation for each level of a categorical
variable.
For example:
category 1: 70+-2.0
category 2: 71+-3.5
category 3: 72+-4.5
category 4: 73+-2.5
category 5: 74+-1.5
Ideally, I'd like a scatter plot like appearance so that each category
has a point (the mean) with whiskers (std dev).
Is this possible is Stata?
Thank you.
Mike
