解析几何概率统计
本范例通过识别数据中的显著偏差来计算四分位差。核心数学概念包括数据的排序、四分位数和四分位差。使用了GeoGebra中的命令如TextField、Polygon、Segment、Sort等进行数据排序和图形展示。适合初中及以上学生学习数据统计与分析。

GeoGebra 命令及参数

  1. Textfield(d1) → inputD1
  2. Polygon((0, 11), (If[showSteps > t0, t1, t2], 11), (If[showSteps > t0, t1, t2], 12), (0, 12)) → tableHeader, b, c, d, e
  3. Segment((0, 10), (If[showSteps > t0, t1, t2], 10)) → f
  4. Segment((0, 9), (If[showSteps > t0, t1, t2], 9)) → g
  5. Segment((0, 8), (If[showSteps > t0, t1, t2], 8)) → h
  6. Segment((0, 7), (If[showSteps > t0, t1, t2], 7)) → i
  7. Segment((0, 6), (If[showSteps > t0, t1, t2], 6)) → j
  8. Segment((0, 5), (If[showSteps > t0, t1, t2], 5)) → k
  9. Segment((0, 4), (If[showSteps > t0, t1, t2], 4)) → l
  10. Segment((0, 3), (If[showSteps > t0, t1, t2], 3)) → m
