This example demonstrates the generation of a scatter plot based on data correlation. Core math concepts include correlation, scatter plot, ratios, integers, integral calculus, and circumcircle. It utilizes GeoGebra commands/objects like Sequence, SD (standard deviation), and Mean. Suitable for high school and above, focusing on data distribution and correlation analysis.

GeoGebra Commands & Parameters

  1. Sequence(Random[0, 10], n, 1, 20) → Y
  2. SD(Y) → sdy
  3. Mean(Y) → meany
  4. Sequence(Random[0, 10], n, 1, 20) → X
  5. SD(X) → sdx
  6. Mean(X) → meanx
  7. Sequence((X(n) - meanx) / sdx, n, 1, 20) → Xnorm
  8. Sequence((Y(n) - meany) / sdy, n, 1, 20) → Ynorm
  9. Sequence((Xnorm(n), Z(n)), n, 1, 20) → Points
