Statistical Inference and Techniques -- Sampling Distributions

Resources
View Resource ** Sampling Distributions

This applet simulates and plots the sampling distribution of various statistics (i.e. mean, standard deviation, variance). The applet allows the user to specify the population distribution, sample size, and statistic. An animated sample from the population is shown and the statistic is plotted. This can be repeated to produce the sampling distribution of the statistic. After the sampling...

View Resource **Inference for Means Activity

This activity enables students to learn about confidence intervals and hypothesis tests for a population mean. It focuses on the t-distribution, the assumptions for using it, and graphical displays. The activity also focuses on how to interpretations a confidence interval, a p-value, and a hypothesis test.

View Resource **Reese's Pieces Samples

This applet simulates drawing samples of Reese?s Pieces from a candy machine. Users set the sample size, number of samples, and theta, the population proportion of orange pieces. The applet keeps track of each sample and displays a dotplot of the sample proportion of orange pieces. Users can also count the number of samples below, above, or between two proportions and superimpose the normal...
