My first guess is that you tried to use Mean before loading the package
DescriptiveStatistics, and you ran into a shadowing problem. Try a new
session and load the package before attempting to use any of its functions.
It works all right. Whenever you get into this problem, i,e,, calling a
function prior to loading the respective package, use Remove to remove the
name of the function and then try again.

<< "Statistics`DescriptiveStatistics`"

data = {4.3, 7.2, 8.4, 5.8, 9.2, 3.9}
Out[2]=
{4.3, 7.2, 8.4, 5.8, 9.2, 3.9}
In[3]:=
Mean[data]
Out[3]=
6.466666666666666
In[4]:=
Variance[data]
Out[4]=
4.6946666666666665
