The user can change the sample size and the number of samples. By using first candies, then a web applet, and varying sample size, students learn that larger samples give more stable and better estimates of a population parameter and develop an appreciation for factors affecting sampling variability. Ask them to write down the number of oranges they might expect for these 10 samples. Many of the topics that students in an introductory statistics course struggle with e. Students then use an actual sample of Reese's pieces candy to calculate a sample proportion, and then compare results for different samples, taken by each student in the class. The user can choose to count the successes greater than a certain value.

NextDiablo Valley College is happy to announce that nationally prominent statistics educators Alan Rossman and Beth Chance of Cal Poly will be leading a practical, two-day workshop on teaching statistics Friday May 10 and Saturday May 11. Now, count the colors for your sample and record the number of each color as well as the proportion of each color sampled from the 25. People who have counted lots of Reese's pieces came up with this number. There are engaging graphics included in many of the applets like the Random Babies applet and the Reese's Pieces applet and the collection is well organized. They are also able to view theoretical values. The data analysis applets are particularly strong and include good step-by-step instructions and thought-questions for the students. You will then have the option of selecting resources within the section or going directly to a specific chapter.

NextI regularly use this collection in my own courses to help students better grasp complex ideas and concepts. Uses pi instead of p for the population proportion, but this notation is used in many not all books. Beth Chance is Professor of Statistics at Cal Poly - San Luis Obispo. The top plot is of the average year drawn and the lower plot is of the average year of all of the samples. Once nice new addition to the collection--for some applets e. He has served as Chief Reader for the Advanced Placement program in Statistics and as Program Chair for the U. Please refer to the style manuals in the area for clarifications.

NextBy using these applets, students can discover patterns in data that might not be otherwise seen e. Unless those who come to this collection have some familiarity with other work by Rossman and Chance e. The probability applets are easier to understand without instructions. You will be given a cup that is a random sample of Reeses pieces. With questions or to sign up from the Contra Costa Community College District contact Read Vanderbilt at rvanderbilt dvc.

NextOne sample of 25 candies will be taken and the proportion of means for this sample is plotted on the graph. Next, students will use the Web Applet Reese's Pieces at rossmanchance. High school instructors will also gain numerous activities and instructional guidance that they can use in the classroom. We cannot offer interpretations about citations as this is an automated procedure. We offer suggestions for implementing the activities throughout the workshop, and we also highlight common student misconceptions to be aware of. This applet simulates the binomial distribution.

NextInstead of trying this activity again with fewer or more candies, simulate the activity using a web applet. She She has co-authored textbooks on teaching introductory statistics with active learning and has conducted more than 100 workshops and given more than 100 presentations on teaching statistics. The instructor can think of creative ways to use these applets without being limited by instructions. Welcome to the Web site for Workshop Statistics: Discovery with Data, Fourth Edition by Allan J. First, students estimate the proportion of orange Reese's pieces in a random sample of 25 candies. How does it compare to the center of the class distribution? You will see that the proportion of orange is already set at. Describe its shape, center and spread.
