Geometric Mean
https://en.wikipedia.org/wiki/Geometric_mean
(Interesting to note on about Aspect Ratios)
Harmonic Mean
https://en.wikipedia.org/wiki/Harmonic_mean
(Interesting to note on Average Speed)

Example: FIX 4
Data: 3, 3, 4, 6, 22
Each new problem must clear "Statistic Register"
[f] [∑] // Clear Statistic Registers
3 [R/S] display 1.0000
3 [R/S] display 2.0000
4 [R/S] display 3.0000
6 [R/S] display 4.0000
22 [R/S] dispay 5.0000
When finish with all the data press 0 [R/S] to find GM and HM
0 [R/S] display 5.4372 [X<>Y] 4.4295
Answer: GM = 5.4372 and HM = 4.4295
