scrnGC2: Calc Input
scrnGC3: f(x) Plot Input
scrnGC4: g(x) Plot Input
The inputs above will be hidden when the program finally gets launched. Currently, I am not hiding them even when you close the calculator. The purpose of the inputs is to help in debugging. This allows you to enter simple code on the calculator screen but the program translates the input to javascript math. Give it a try and see if you notice any obvious problems or have suggestions for improvements.
Box and Whiskers Diagrams
Valid HTML 4.0 Transitional
The primary purpose of this lesson is to illustrate how to create a box and whiskers diagram.

Given a data set, sort the data and calculate the following:

  • Minimum and maximum.
  • The median of the data.
  • The lower and upper quartile (Q1 & Q3).
  • The interquartile range (IQ).
Any number less than Q1 - 1.5•IQ or greater than Q3 + 1.5•IQ is considered an outlier.
