 Control Charts These applets, created by Virginia Tech's Department of Statistics, allow you to see how the common Xbar control chart is constructed with known variance. The Xbar chart is constructed by collecting a sample of size n at different times t. The process is considered to be out of control if the sample mean of the current sample falls above or below the control limits. The user has the options to... https://www.causeweb.org/repository/statjava/ControlCharts.h...
 Data Analysis The applet, created by Virginia Tech's Department of Statistics, allows for simple data analysis of univariate data. Users can either generate normal or uniform data for k samples or copy and paste data from another source to a text box. A univariate analysis is performed for all k samples. A two-sample t-test (Pooled and Satterthwaite) is performed for k = 2. An ANOVA test is performed for k > 2. https://www.causeweb.org/repository/statjava/Data.html
 Introduction to Minitab Created by Ginger Rowell of Middle Tennessee State University, this laboratory introduces students to the basics of the Minitab software. Students make use of a basic example (water consumption and temperature) to introduce students to manipulation of data, calculation of descriptive statistics, creation of histograms, boxplots and scatterplots. Students are asked to hand in the results they... https://www.causeweb.org/repository/
 Exponential Probabilities The applet, created by Virginia Tech's Department of Statistics, allows you see how probabilities are determined from the exponential distribution. The user determines the mean of the distribution and the limits of probability. Three different probability expressions are available. Click "Calculate" to see the pdf and the cdf. The probability is highlighted in green on the pdf. This is a nice... https://www.causeweb.org/repository/statjava/ExpDensity.html
 Correlation The applets, created by Virginia Tech's Department of Statistics, allow you to see how different bivariate data look under different correlation structures. The "Movie" applet either creates data for a particular correlation or animates a multitude data sets ranging correlations from -1 to 1. The "Creation" applet allows the user to create a data set by adding or deleting points from the screen. https://www.causeweb.org/repository/statjava/Correlation.htm...
