3. Divide the result above by n = 10:
4. Apply the INV() function to the latest result:
Thus, the harmonic mean of list S is s

= 1.6348…
Geometric mean of a list
The geometric mean of a sample is defined as
To find the geometric mean of the list stored in S, we can use the following
procedure:
1. Apply function ΠLIST() to list S:
2. Apply function XROOT(x,y), i.e., keystrokes ‚», to the result in 1:
