Applets Illustrating Topics in Introductory Statistics
- Guess the correlationsof random scatterplots of points.
- Draw your best guess at a regression line and see how well you do compared to the least squares line.
- See how individual points can affect regression lines.
- Select the different animate options and see how the slope, SE and SDx change.
- Use Venn Diagrams to see how the probabilities and conditional probabilities change with changing events A and B.
- Investigate the effects of changing the standard deviation on the shape of the normal distribution.
- Simulations of interesting problems in probability, including the birthday problem, the coupon problem, and Banach's matchbox problem.
- Some very challenging problems in probability: these require some hard thinking!
- Dice Rolling
- Simulation of the Monte Hall problem: should you switch doors or not?
- Normal approximation to the binomial.
- Ball drop that simulates a normal distribution.
- A demonstration of the central limit theorem with skewed distributions.
- Confidence interval coverage.
