mean function returns dimensionless quantities

[mattyd100]

When I calculate the mean of a quantity (such as multiple length measurements), a dimensionless value is returned. Shouldn't it have units? Or am I missing something?

`import numpy as np
import pint

ureg = pint.UnitRegistry()
length = np.array([1, 2, 3]) * ureg('in')

print(statistics.mean(length))`

the statistics doesn't have support for pint. you can use np.mean instead
