-1-1Simulating Confidence Intervals
https://www.merlot.org/merlot/viewMaterial.htm?id=221221
This applet allows users to generate confidence intervals for either means or proportions. Users set the parameters including the number of samples and click "Sample." The applet graphs the intervals such that intervals containing the true mean or proportion are in green, while intervals not containing the true mean or proportion are in red. The true mean or proportion is shown by a blue line.Mon, 09 Oct 2006 18:08:11 GMTAllan Rossman; Beth Chance California Polytechnic State University; California Polytechnic State UniversityBuffon's Needle
https://www.merlot.org/merlot/viewMaterial.htm?id=233135
This applet provides a simulation of Buffon's Needle experiement. A needle of length 1 being dropped at random on a floor covered with boards of width 1. Users can drop 1, 2, 10, or 20 needles. Blue needles do not cross the crack between two boards; red needles do. If <em>X</em> represents the ratio of crossings to attempts, then <em>2/X</em> should approach a familiar number, Pi.Tue, 02 Jan 2007 22:31:42 GMTCharles Stanton CSUSBConfidence Intervals
https://www.merlot.org/merlot/viewMaterial.htm?id=245307
<p>This applet generates confidence intervals for means. Users can set the confidence level to .8, .9, .95, or .99 and can sample one or 50 times at once. The applet shows the normal distribution with the mean shown as a green line. Confidence intervals shown in black contain the true mean, while those that do not are shown in red. The applet keeps track of the number of intervals generated, the number that contain the mean, and the percent that contain the mean.</p>Tue, 13 Mar 2007 19:31:03 GMTWilliam Notz; David Moore The Ohio State University; Purdue UniversityMaximum Likelihood

https://www.merlot.org/merlot/viewMaterial.htm?id=233072
This data file comes from the Data and Story Library (DASL). It gives eleven characterisitcs of 478 students in grades 4-6 and asks students to determine which characteristics make a person popular. Students will use mean ranks and summary statistics when analyzing this dataset.Tue, 02 Jan 2007 21:53:34 GMTPaul Velleman; Matthew Hutcheson; Mike Meyer Cornell University; Cornell University; Carnegie Mellon UniversityTools for Teaching and Assessing Statistical Inference: Sampling SIM
https://www.merlot.org/merlot/viewMaterial.htm?id=242444
This website helps students learn concepts underlying statistical inference, through the simulation software, Sampling SIM. This software lets students explore sampling distributions by building population distributions, taking random samples, and exploring the behavior of sampling distributions and confidence intervals. The site includes instructional modules and assessment instruments. Key words: measures of center, sampling, sampling distribution, confidence interval, p-values, powerThu, 22 Feb 2007 15:16:53 GMTBob delMas; Beth Chance; Joan Garfield University of Minnesota; California Polytechnic State University; University of MinnesotaDraft Lottery
https://www.merlot.org/merlot/viewMaterial.htm?id=233083
This data file comes from the Data and Story Library. It contains the 1970 draft data including month, day of month, day of year, and draft number. Students will use scatterplots and correlation to see if there is a relationship with birthdate and draft number. On first glance, there appears to be no relationship, but looking at side-by-side boxplots reveals an interesting twist. The data set is in text format.Tue, 02 Jan 2007 22:00:20 GMTPaul Velleman; Matthew Hutcheson; Mike Meyer Cornell University; Carnegie Mellon UniversityP-Value of a Test of Significance
https://www.merlot.org/merlot/viewMaterial.htm?id=245313
This applet illustrates the p-value of a test of significance for means. Users set the null and alternative hypotheses, sample size, and standard deviation. The applet allows users to use the mean of data they have already collected or to generate a random sample of data based on a population mean. The normal distribution is shown and the p-value is highlighted in yellow.Tue, 13 Mar 2007 19:38:59 GMTWilliam Notz; David Moore The Ohio State University; Purdue UniversityRowers vs. Coxswain
