I have always thought that the operation:
((sum(x1-(x-ave))^2)...XN-(x-ave))^2/(N-1))^.5
was known as the standard deviation. But now my physics text says that it is:
((sum(x1-(x-ave))^2)...XN-(x-ave))^2/(N))^.5
and another website I went to says that yes, the second equation is the correct terminology and that the first equation is the square root of the bias-corrected variance, and that the two are often confused. So what operation does the "standard deviation"
operation on my TI-89 do? and how do I do the other one?
