Confidence intervals

Choose the size of the horseshoe (from 1 = smallest to 10 = largest), then press a numbered button to see that number of tosses.

Analogies:
  1. Horseshoe = Confidence interval
  2. Stick = Population parameter
  3. Chance of covering the stick = Chance the confidence interval covers the population parameter
  4. One toss = confidence interval calculated from a sample
  5. The larger the confidence interval (horseshoe), the larger the coverage probability.
  6. The confidence interval (horseshoe) is random, not the population parameter (stick).
