The Mean Machine
See how the Arithmetic Mean (or Average) is calculated:
../numbers/images/mean-machine.js
Things to Try:
- Create an outlier: Enter one very large value and notice how much it pulls the mean up
- Try all negatives. How does that affect the mean?
- Find the balance: Can you make the mean 0?
- Zeros: Add some zeros, how do they affect the mean?
- Fair share: Try having all the values equal
