Biology stats - standard deviation
I was just wondering, what is the minimum "n" can be to calculate standard deviation? Thanks!
For an unbiased estimator based on a sample, the sample size would have to be two at least.
You guys I'm doing A2 CIE biology. When it asks for standard deviation, why can't I use the normal formula from stats rather than the one they are giving? It's honestly takes so much more time to use the other one!

Which one do you use for stats? Which one do you use for biology? I may be able to shed some light on it.
Either type them up in LaTeX, or scan them or take a photo.
