With this app you can explore basic statistics concepts, compare different models and see how they all boil down to the same recipe:
Data = model + error
Model Comparison Approach: Model 1
Model 1 uses one metric independent variable and a metric dependent variable and offers a basic introduction of the model comparison approach and an introduction to model comparison using linear regressions and correlations.
Model Comparison Approach: Model 2
Model 2 uses one categorical independent variable and a metric dependent variable and offers a more advanced discussion using linear regressions with dummies, t-test, and factorial ANOVA.
