Since we are talking about JMeter, it is the mean, deviation and median for the
response times. This means milliseconds. Therefore:
mean = sum(data)/count
deviation = SD = sqrt { sum(x - mu)^2 / (n-1) },
median = look at this page for an explanation http://www.mathsisfun.com/median.html
Here is a link to an applet that calculates standard deviation.
http://www.netsoc.tcd.ie/~jgilbert/maths_site/applets/algebra/standard_deviation____explanation_and_calculation_.html
also, if you use excel, it has all these math functions and you can look it up. I hope
that answers your question. Here is the link to the explanation of the graph results.
By the way, all these docs are part of the JMeter distribution, so you already have
them.
