SequenceProbability & Statistics
This example illustrates the concepts of center and spread, including mean and standard deviation. Using GeoGebra commands like Sequence and Element, it dynamically shows the central tendency and dispersion of a dataset. Suitable for statistics and probability studies.

GeoGebra Commands & Parameters

  1. Sequence(Mod[8 + (23 * k), 48] + 100, k, 0, 47) → ChNmSq
  2. Element(ChNmSq, Seed) → ChNm1
  3. Mod(ChNm2, 2) → Op2
  4. Mod(ChNm1, 2) → Op1
  5. If(Op1 ≟ 0, "minimum", "maximum") → MnOrMx
  6. If(Op2 ≟ 0, "decreases", "increases") → DnOrUp
  7. If(Op1 ≟ 0, If[Op2 ≟ 0, "increases", "decreases"], If[Op2 ≟ 0, "decreases", "increases"]) → SpDr
  8. Mod(ChNm3, 6) → Op3
  9. Sequence(Mod[Str + k, 6] + 1, k, 1, 3) → ObChSq
  10. Text("mean") → Ob1
  11. Text("median") → Ob2
  12. Text("midrange") → Ob3
  13. Text("range") → Ob4
  14. Text("standard deviation") → Ob5
  15. Text("interquartile range") → Ob6
  16. Element(ObSq, Element[ObChSq, 1]) → ObA
  17. Element(ObSq, Element[ObChSq, 2]) → ObB
  18. Element(ObSq, Element[ObChSq, 3]) → ObC
  19. Element(AnSq, Element[ObChSq, 1]) → ChA
