I'm a programmer, with a decent but not-expert knowledge of stats, and I'm working through these instructions for how to create funnel plots.
I understand from a previous question that the standard error in these instructions is being calculated using
p(1-p) (in step 4), because these are events and therefore follow a Bernoulli distribution.
However, if the data was about individuals in the population, rather than events, how would I calculate the standard error?
I know it would be a Normal distribution and therefore standard error would be the square root of the standard deviation, but what formula would I calculate that, given the data I have in the example? (i.e. a set of samples with denominator and numerator population).
Thanks for your help.
