In MSA fourth version, Guidelines for determining bias:
analysis of results - numerical
sigma repeatability = sigma r = sum(Xi-Xbar)^2/(n-1)
Is it correct?
I think it should be = (sum(Xi-Xbar)^2/(n-1))^0.5
or (sigma r)^2 = sum(Xi-Xbar)^2/(n-1)
Because in the following page example-bias
sigma r = 0.212019765 [=(sum(Xi-Xbar)^2/(n-1))^0.5]
instead of 0.044952381 [=sum(Xi-Xbar)^2/(n-1)]
