STAT2507A – Lab 2 – June 8, 2009 Introduction In this lab you will randomly generate data to check Tchebysheff's theorem and the Empirical  Rule. You will apply the following class concepts: - Tchebysheff's theorem, the empirical rule, descriptive statistics, histograms. Learning objectives: 1. Generating random data 2. Verify Tchebysheff's theorem 3. Verify the Empirical Rule 4. Using descriptive statistics to describe data 5. Working with histograms Objective 1: Generating random data Being able to randomly generate data is an important part of doing statistics. Selecting samples,  or getting test data to test systems are some examples of the uses of random data.  For this lab, you will generate random data from various common probability distributions and  verify Tchebysheff's theorem, and the empirical rule. 1) Random data can be generating by going to Calc -> Random Data -> {a distirbution}. Start  with the Normal distribution. 1

Fill in the resulting dialogue. You need to provide the number of random number to  generate, the column to store it in, a mean and a standard deviation (it does not matter  what numbers you use for this exercise, just generate at least 250 observations). 2
