http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1734
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1734This activity is an example of Cooperative Learning in Statistics.It uses student's own data to introduce bivariate relationship using hand size to predict height. Students enter their data through a real-time online database. Data from different classes are stored and accumulated in the database. This real-time database approach speeds up the data gathering process and shifts the data entry and cleansing from instructor to engaging students in the process of data production.Key words: Regression, correlation data collection, body measurementsWed, 30 Dec 2009 12:44:32 -0500Song: The Bootstrap Begins

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1793
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1793This FLASH based applet illustrates the sampling distribution of the mean. This applet allows the user to pick a population from over 2000 pre-defined populations. The user can then choose size of the random sample to select. The applet can produce random samples in one, 10, 100, or 1000 at a time. The resulting means are illustrated on a histogram. The histogram has an outline of the normal distribution and vertical lines at 1, 2, and 3 standard deviations. The applet can be viewed at the original site or downloaded to the instructors machine.Sat, 26 Jan 2008 05:00:45 -0500A Brief Introduction to Bayesian Statistics

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1746
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1746In this hands-on activity, students count the number of chips in cookies in order to carry out an independent samples t-test to see if Chips Ahoy® cookies have a higher, lower, or different mean number of chips per cookie than a supermarket brand. First there is a class discussion that can include concepts about random samples, independence of samples, recently covered tests, comparing two parameters with null and alternative hypotheses, what it means to be a chip in a cookie, how to break up the cookies to count chips, and of course a class consensus on the hypotheses to be tested. Second the students count the number of chips in a one cookie from each brand, and report their observations to the instructor. Third, the instructor develops the independent sample t-test statistic. Fourth, the students carry out (individually or as a class) the hypothesis test, checking the assumptions on sample-size/population-shape.

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1745
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1745This hands-on activity is appropriate for a lab or discussion section for an introductory statistics class, with 8 to 40 students. Each student performs a binomial experiment and computes a confidence interval for the true binomial probability. Teams of four students combine their results into one confidence interval, then the entire class combines results into one confidence interval. Results are displayed graphically on an overhead transparency, much like confidence intervals would be displayed in a meta-analysis. Results are discussed and generalized to larger issues about estimating binomial proportions/probabilities.Tue, 22 May 2007 02:02:12 -0400A ducks story- introducing the idea of testing (statistical) hypotheses
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1744
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1744By means of a simple story and a worksheet with questions we guide the students from research question to arriving at a conclusion. The whole process is simply reasoning, no formulas. We use the reasoning already done by the student to introduce the standard vocabulary of testing statistical hypotheses (null & alternative hypotheses, p-value, type I and type II error, significance level). Students need to be familiar with binomial distribution tables.After the ducks story is finished, the class is asked to come up with their own research question, collect the data, do the hypotheses testing and answer their own research question. The teaching material is intended to be flexible depending of the time available. Instructors can choose to do just the interactive lecture type, interactive lecture + activity, or even add the optional material.

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1743
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1743The purpose of this activity is to enhance students' understanding of various descriptive measures. In particular, by completing this hands-on activity students will experience a visual interpretation of a mean, median, outlier, and the concept of distance-to-mean.Tue, 22 May 2007 01:42:03 -0400Psychic test
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1742
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1742This activity illustrates the convergence of long run relative frequency to the true probability. The psychic ability of a student from the class is studied using an applet. The student is asked to repeatedly guess the outcome of a virtual coin toss. The instructor enters the student's guesses and the applet plots the percentage of correct answers versus the number of attempts. With the applet, many guesses can be entered very quickly. If the student is truly a psychic, the percentage correct will converge to a value above 0.5.Tue, 22 May 2007 01:36:11 -0400Count the Fs: Why a Sample instead of a Census?
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1741
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1741This interactive lecture activity motivates the need for sampling. "Why sample, why not just take a census?" Under time pressure, students count the number of times the letter F appears in a paragraph. The activity demonstrates that a census, even when it is easy to take, may not give accurate information. Under the time pressure measurement errors are more frequently made in the census rather than in a small sample. Tue, 22 May 2007 01:25:35 -0400
