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
