• ### Boxplot

This site give a definition and an example of boxplots. Topics include outliers, medians, as well as lower and upper quartiles.
• ### ANOVA for Regression

This site gives an explanation, a definition and an example of ANOVA for regression. Topics include analysis of variance calculations for simple and multiple regression, and F-statistics.
• ### Experimental Design

This site gives an explanation, a definition of and an example using experimental design. Topics include experimentation, control, randomization, and replication.
• ### Sampling in Statistical Inference

This site gives an explanation, a definition and an example of sampling in statistical inference. Topics include parameters, statistics, sampling distributions, bias, and variability.
• ### RVLS Case Studies

This site provides case studies which cover subject areas including: analysis of variance, boxplots, confidence intervals, contrast among means, correlated t-test, correlation, histograms, independent groups t-test, regression, repeated measures ANOVA, and t-tests.
• ### Analysis Tool: Create a Pie Chart

This resource defines a pie chart. It also allows the user to input values to create their own graphs. The user has control over the title, up to 15 slices, the color of each slice, and can choose a 3-D option.

• ### Binomial Probability Model

This resource defines and explains binomial probability, including examples and exercises for the learner.
• ### Statistical Education through Problem Solving

This resource includes problem-based teaching and learning materials for statistics that are based around specific problems arising in biology, business, geography and psychology. The STEPS modules are intended to be used as problem-based lab material that may support existing coursework.
• ### Histogram

This activity allows the user to create and manipulate histograms with built-in or user-specified data, and provides links to discussion and exercise questions. The mean and standard deviation of each data set are also calculated and the bin width of each histogram can be changed by the user.
• ### Using Data and Statistics

This site addresses mean, median, mode, bar graphs, pie charts, and line graphs. Each topic has multiple examples with related discussion.
