Using an Applet to Demonstrate the Sampling Distribution of an F-statistic part of CAUSE Teaching Methods:Interactive Lectures:Examples
This visualization activity combines student data collection with the use of an applet to enhance the understanding of the distributions of mean square treatment (MST), mean square error (MSE) as well as their ratio, an F-distribution. Students will see theoretical distributions of the mean square treatment, mean square error and their ratio and how they compare to the histograms generated by the simulated data.

Investigating the Modernity of the University Library part of CAUSE Teaching Methods:Campus-Based Learning:Examples
Students will investigate the modernity of the university library by designing and implementing a complex survey design.

Influence of Outliers on Correlation part of CAUSE Teaching Methods:Teaching with Data Simulations:Examples
In this visualization activity, students will observe their instructor create a scatterplot and observe how the correlation coefficient changes when outlier points are added. Students are then given a follow up assignment which guides them through the applet. In addition, the assignment provides insight about outliers and their effect on correlation.

Using an Applet to Demonstrate Sampling Distributions of Regression Coefficients part of CAUSE Teaching Methods:Interactive Lectures:Examples
This applet simulates a linear regression plot and the corresponding intercept and slope histograms. The program allows the user to change settings such as slope, standard deviation, sample size, and more.

Using an Applet to Demonstrate a Sampling Distribution part of CAUSE Teaching Methods:Interactive Lectures:Examples
Introducing sampling distribution through cooperative learning among students using a group activity. Afterwards, use the sampling distribution applet to illustrate.

Correlation Guessing Game part of CAUSE Teaching Methods:Games:Examples
In this game activity, students match correlation values with plots generated by the applet. Competition in this game setting encourages students to become more involved in the classroom and attainment of learning objectives.

Interpreting Graphical Displays of Univariate Distributions part of CAUSE Teaching Methods:Gallery Walks:Examples
Students give practical interpretation of graphs based on shape, center, and spread.
