Instructors can demo and students can get a feel for regressions. In a regression for housing prices slope and intercept can be changed and the results are displayed in a diagram together with the equation and the MSE.

500 combinations of sq ft and housing prices from the Boston Housing dataset are displayed in a scatter diagram. By changing slope and intercept a regression line can be added to the scatter diagram. The underlying equation as well as the MSE and the MAE are calculated dynamically

The simulation introduces empirical vs. theoretical probabilities. It shows how probability can be obtained using the concepts of theoretical and empirical probabilies based on an experiment flipping three chips with each having a red and a yellow side.
