Thread: Statistics Basics (Updated)

Per request, I've modified the statistics calculator to also determine median and mode of a number set including color coding of the number(s) used for the median and mode. This is an enhancement to the original program that calculates mean, variance, and standard deviation of a number set.

The original url is the same as the posts in the statistics threads here at MHF.

Simply enter a number set separated by commas and press the button. I've seen conflicting writeups on different websites regarding mode. Some say that if no numbers in a number set such as (1,2,3,4,5) have a frequency more than 1 time, no mode exists. Others say that same number set has a mode of (1,2,3,4,5). I setup the calculator to display the first option in that case.

Search engine is set to pick up keywords such as mean, variance, standard, deviation, mode, median, number set.

Let me know if you want enhancements or see errors.

A stem and leaf plot, ranked data set, harmonic mean, and geometric mean have been added to this lesson.
