(11C) The Four Means
The following program uses the statistical registers to calculate four types of mean:
Arithmetic Mean: μ = Σx / n Harmonic Mean: HM = n / Σ(1/x) Geometric Mean: GM = (Πx) ^ (1/n) Root Mean Square: RMS = √(Σx^2 / n) The HP 11C uses the following registers in statistical analysis. Be sure to clear registers by pressing [ f ] [ x<>y ] (CLEAR REG) before beginning. R0 = n R1 = Σx R2 = Σx^2 R3 = Σy R4 = Σy^2 R5 = Σxy LBL A: Enter data LBL B: Analysis: μ [R/S], HM [R/S], GM [R/S], RMS HP 11C Program: The Four Means Code:

RE: (11C) The Four Means
Good work Eddie! I had a lot of fun with your program for finding the 4 different means and I can see you put a lot of work into your blog. It's like a form of retreat for me.
I ran your program and I got every mean except the geometric mean. I checked all my inputs as well as checked my program for any errors and detected none. After entering your example into my 11C emulator, my register 7 has a 0.0000 in it, which leads me to believe that the STO * 7 is not working as intended.

It's like a form of retreat for me. I forgot to say store 1 in register 7 first before running the program. Thanks for reminding me!
