|| Unit Circle
|| Geometric interpretation of the sine and cosine functions using
a cirlce with radius of one.
|| Spell test
|| Can you choose between correctly and incorrectly spelled versions of
21 difficult words?
|| SLR model
|| Simulate from the simple linear regression model. The focus is on
the differences between the parameters and their estimates and between
the errors and the residuals
| Power curve
|| Power curve for the two-sample t test and its dependence on the
effect size, standard deviation, sample size, and significance level
| Norm Quant Plot
|| Produces normal quantile plots for simulated data from different distributions
(normal and non-normal) and explains what is plotted on the x- and y-axes.
|| Displays how leverage is a measure of the statistical distance of the x-
values for an individual from the center of the x-values for the dataset.
| Model Selection
|| Shows the bias/variance tradeoff involved in model selection. Specifically,
underfitting can lead to bias in the regression coefficient estimates and overfitting
can lead to increased variance.
|| One-way fixed/random effect models
| Three Factor
|| Shows the effects of each term in the 3-factor effects model on the cell means
| Two factor
|| Simulating from two-factor models with crossed/nested and
