The documentation isn't clear as to the difference between mu and xbar, and why one is used in variance and the other in pvariance. See #36018 for discussion. For the record: mu or μ is the population parameter, i.e. the mean of the entire population, if you could average every individual. xbar or x̅ is the mean of a sample.
