Lab4.3: The Central Limit Theorem

Introduction:

In this lab you will use computer simulation to demonstrate the Central Limit Theorem, one of the most important theorems in statistics. As you know from the text, the Central Limit Theorem states that regardless of the population we take our data from, the sample mean of a random sample will have approximately a normal distribution if the number of observations in that sample is large enough and if the population obeys certain conditions. In the following you can explore the practical implications of this theorem through computer simulation.

Getting Started:

To navigate through the lab, use the menu bar on the left side of this window, which will be available to you throughout the lab. The "Glossary" section will provide you with a brief refresher on the terms and concepts you need to know for this lab. Click "Applet" to open the applet for this lab. Once you open the applet, there will be specific step-by-step instructions found at the bottom of the applet window. When all instructions have been completed, close the applet window. You may then be instructed to answer the summary questions. Even if you are not, have a look: they will be a good test of your understanding.
