Activity

Use the applet to explore the size of the standard deviation as you change the distribution on the grid.

Set the number of rows to 6 and the number of columns to 10. Investigate the following:
  1. What is the smallest value of the standard deviation that you can find for a distribution involving at least two distinct numbers (that is, at least two different columns should be shaded)?
  2. What is the largest value of the standard deviation that you can find for a distribution involving at least two distinct numbers?
