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
