The Poisson Distribution

This applet computes quantities related to the Poisson Distribution.

How to use the applet

  1. In the upper-left table, enter values for eqn and a constant, c. The value of eqn must be a positive number less than or equal to 60, and c must be a nonnegative integer less than or equal to 150. Note, these cells act like a spreadsheet application; to change an entry, click on it, delete the current value, type a new one, and then press enter.
  2. A probability histogram is plotted below the table of parameters. You may choose to shade different regions of the histogram, eqn, eqn, or eqn, and the highlighted region will turn red. Next to your choice, the quantities eqn, eqn, and eqn are shown.
  3. You may generate a sample of size eqn from the given Poisson distribution by entering a value for eqn in the lower-left table. eqn must be a positive integer less than or equal to 20,000. For each sample, the statistics eqn and eqn computed by substituting eqn for eqn will be shown.
