Distribution of Sample Mean

This applet computes the distribution of a sample mean from a user-specified population.

How to use the applet

  1. Enter a population of five items at the top of the applet. 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. The applet plots a line graph of the population and computes the population mean and standard deviation.
  2. Below the population plot, choose a sample size from 1 to 5. The applet computes all possible samples of that size drawn from the population with replacement. Along with each sample, the applet displays the sample mean and the probability of that sample. The applet plots all the sample means below the table of the samples.
