I'm hoping there's a straightforward answer to this (that isn't "no") :tup:

For some data I know the mean, the upper and lower quartile figure, and also the number of observations on which it is based. I would like to know the standard error.

Is there a way of working this out? Even if only an estimation. I know Excel has the Solver function, but I don't really know how to use that or if it could even do it if I wanted it to.

Any ideas?

Thanks,

Chris
