>>12281719>meanNo, physics dude. Thats not the mean. That's called sample average.
>varianceNo, physics dude. That's not the variance. That's the sample squared deviation from the mean. It's a biased estimator of the variance. You simply dont use that.
>standard deviationNo, dude. Thats the sample standard deviation. You dont use sigma. What if you square it? Do you get your 'variance'? Abhorrent.
