Perhaps there's something that escapes me. I think that never or almost never one can find that four times standard deviation is greater than range (no hypothesis at all). The same data is used to compute range and standard deviation, so it should be very strange to see that one gives a very different evidence than the other. They are simply two different indexes of the same variability.

It gives me runtime errors how do i solve it?
I look it up on google it gave me

what is runtime error

dan

even when you have a variation larger than stdev, it only shows correlation, not necessarily causality.

but there is some problem of circular argument in your analysis. you should use this stdev to check the variation in another data set (not this particular one), e.g. different year in this zip or data in another zip.

btw, a nice blog you have :)
