Objectives In this activity, you will use the applet for investigating the sampling distribution of . You will use the applet to explore the shape of the sampling distribution when the population is normally distributed and when the population is not normal. Materials Computer with internet access - one per student or pair of students. Launch the Sampling Distributions applet at http://onlinestatbook.com/stat_sim/sampling_dist/index.html. When the BEGIN button appears on the left side of the screen, click on it. You will see a yellow page entitled "Sampling Distributions". 1. There are choices for the population distribution: Normal, uniform, skewed, and custom. The default is Normal. Click the "Animated" button. What happens? Click the button several more times. What do the black boxes represent? What is the blue square that drops down onto the plot below? What does the red horizontal band under the population histogram tell us? Notice the left panel. Important numbers are displayed there. Did you notice that the colors of the numbers match up with the objects to the right? As you make things happen, the numbers change accordingly, like an automatic scorekeeper. 2. Click on "Clear lower 3" to start clean. Then click on
