Why would I search for the data?
Perhaps because you want to know the answer to your question; or was the question completely rhetorical and you simply wanted to send me on a wild goose chase?
you're the one providing the statistics.
But you are the one questioning them and asking further questions for which you seem not to want the answer. Otherwise, you would take the time and trouble to find out for yourself.
That page contains 0 times the term variance and 1 time the term deviation.
Apparently, it isn't the standard deviation of productivity.
I gave you the official page and you have officially disregarded it. If you want something done right, you should do it yourself.
