The ChanceForge cast

Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.

  1. Tally the Counter-of-Outcomes Data collection + frequency counting (the foundational "what happened, how often?" move)
  2. Display the Picture-Maker Graphs and visual displays (bar charts, histograms, dot plots, line graphs — turning numbers into pictures)
  3. Center the Middle-Finder Central tendency — mean, median, mode (the "what's typical?" question)
  4. Sample the Estimator Sampling, sampling distributions, inference from sample to population
  5. Tree the Compound-Brancher Compound events and probability trees — multiplication rule for independent events, addition for disjoint, conditional dependencies
  6. Odds the Likelihood-Reader Basic probability — placing a chance on the 0-to-1 scale from impossible to certain
  7. Scatter the Spread-Reader Spread and variability — how far apart the data is (range), not just the middle
  8. Flipside the Other-Outcome-Counter The complement rule — find the chance it doesn't happen and subtract from 1
  9. Clew the Clue-Follower Conditional probability — how chances change once you learn a new fact
  10. Evens the Long-Run-Settler Expected value and the long run — results settle toward the average over many tries
