CHEN 3010 Applied Data Analysis Fall 2004 Group Members: __________________________ __________________________ __________________________ __________________________ Workshop 9: Central Limit Theorem Objective: Measurements may exhibit a distribution that is markedly different from the normal distribution; however, when groups of these measurements are combined in a calculation, such as an average, the Central Limit Theorem states that the distribution of the calculated values tends toward a normal distribution, even if the original data definitely do not. In this workshop, you will test the Central Limit Theorem. Directions: 1. Go out the HP Lab Plaza in the ITLL. Rotate group members on the computer, as suggested below, and pay close attention to the operations carried out there. 2. Group Member 1 : Log onto the computer. Launch Excel. 3. Select Tools Data Analysis . [If Data Analysis is not on the Tools menu, select Add-Ins , then check Analysis Toolpak .] Select Random Number Generation . 4. In the Random Number Generation dialog box, set the Number of Variables equal to 20 and the Number of Random Numbers to 200 . Select the Distribution type to be Uniform . Click OK . You should see a matrix of 4,000 random numbers appear on a new worksheet. These follow a uniform , not normal, distribution. 5.
