(12C) Geometric & Harmonic Mean
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

Program:
Code:
 01 X=0 02 GTO 09 03 1/x 04 ENTER 05 LSTx 06 LN 07 ∑+ 08 GTO 00 09 x̄  // X-Bar 10 X<>Y 11 1/x 12 X<>Y 13 e^x 14 GTO 00
