I have not had Statistics since the first time I went to college - 13 years ago, so...

I'm trying to create a Visual Basic program (VB2005) for an Intro to VB 2005 class Thesis project that calculates the following items out of a set of numbers:

  • Mean
    • Arithmetic Mean
    • Weighted Arithmetic Mean
    • Geometric Mean
    • Harmonic Mean
    • Power Mean
    • Interquartile Mean
    • Quadratic Mean
    • Generalized (Power, Holder) Mean
  • Mode
  • Median
    • Standard Median
    • Weighted Median
  • Range
    • Standard Range
    • Interquartile Range


Here is a list of test figures (the total number of figures will vary from job to job): { 1, 1, 1, 1, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5 }

I have the calculations for all the Modes, Medians, and Ranges, and most of the Means, but I either do not have the calculations or understand the calculations for the following Means calculations:

  • Weighted Mean
  • Generalized (Power, Holder) Mean


If anyone is a Statistics master, please help!!!
