FunctionProbability & Statistics
This example demonstrates the concept of standard score. It involves key statistical concepts such as mean and standard deviation. Using GeoGebra commands like If, Segment, Sequence, etc., it visually illustrates the process of data standardization. Suitable for high school and above students to learn probability and data analysis.

GeoGebra Commands & Parameters

  1. If(seed < GMn, -1, 1) → Sgn
  2. Segment(LftEnd, RgtEnd) → Line
  3. Sequence(AF(k), k, LftVl, RgtVl, 10) → TcVlSq
  4. CountIf(x > 0, TcVlSq) → TkCnt
  5. Sequence(Segment[(Element[TcVlSq, k], Hgt - 0.1), (Element[TcVlSq, k], Hgt + 0.1)], k, 1, TkCnt) → TcSq
  6. Vector(MnTl, MnHd) → MnPtr
  7. Vector(DVTl, DataValue) → DVPtr
  8. Segment(MnTl, DVTl) → PtrSg
  9. Sequence(Text[LftVl + ((k - 1) * 10), (Element[TcVlSq, k] - 0.15, Hgt - 0.4)], k, 1, TkCnt) → AxLb
  10. VerticalText("Data Value", DVLP) → DVLbl
  11. VerticalText("Mean", MnLP) → MnLbl_1
  12. Sequence(Segment[(GMn + ((Sgn * k) * GSD), Hgt - 0.9), (GMn + ((Sgn * k) * GSD), Hgt - 1)], k, 1, TkNm) → PtrTSq
  13. Vector(SDP1, SDP2) → SDSgRt
  14. Vector(SDP2, SDP1) → SDSgLf
