Standard Deviant

7:35:06 PM Teleolurian Kordyne: like, if somebody gets a mean 1000 hits to a website per week with a standard deviation of 200 hits, it's only 25% likely that they'll get 1400 hits in a week

7:35:45 PM Teleolurian Kordyne: but another person with 1000 hits a week and a standard deviation of 600 hits is 50% likely to see 1400 hits in a week

7:36:36 PM SGrDDyPiMP: how do you determine standard deviation?

7:37:23 PM Teleolurian Kordyne: get the number of hits for x weeks, find the average, subtract the mean from each week's count, square the counts, add the results, divide by the number of values, sqrt the result

7:37:36 PM Teleolurian Kordyne: simple math

7:38:13 PM SGrDDyPiMP: that makes my brain hurt - which must mean you're touching yourself
