What formula does the banker use in Deal or No Deal?

The banker makes an offer based on the root mean square (RMS) value v of the remaining boxes, which involves squaring the values, taking the mean, and then square rooting again. Basically it’s a fancy term for a middle weighted average, so that any of the extreme values don’t skew the average too much.
