In collections Statistics and Probability with Mr Downes
This applet demonstrates the test scores of 20 students from two classes, A and B, and analyzes the data using statistical characteristics such as mean, median, mode, and standard deviation. Commands like Sort, Intersect, Point, and Sequence are used for data sorting and processing. Suitable for high school statistics education.

GeoGebra Commands & Parameters

  1. Sort(list1) → list1sorted
  2. Intersect(xAxis, yAxis) → A
  3. Point(xAxis) → B
  4. Point(yAxis) → D
  5. Sort(list2) → list2sorted
  6. Sequence(Polygon[(n - 1, 0), (n, 0), (n, Element[list2, n / 2]), (n - 1, Element[list2, n / 2])], n, 2, 42, 2) → list2bars
  7. Sequence(Polygon[(n - 2, 0), (n - 1, 0), (n - 1, Element[list2sorted, n / 2]), (n - 2, Element[list2sorted, n / 2])], n, 2, 42, 2) → list2sortedbars
  8. Point(l1) → O_1
  9. Sequence(Polygon[(n - 2, l1(0)), (n - 1, l1(0)), (n - 1, Element[list1sorted, n / 2] + l1(0)), (n - 2, Element[list1sorted, n / 2] + l1(0))], n, 2 + x(O_1), 41, 2) → list1sortedbars
  10. Sequence(Polygon[(n - 1, l1(n - 1)), (n, l1(n)), (n, Element[list1, n / 2] + l1(n)), (n - 1, Element[list1, n / 2] + l1(n - 1))], n, 2 + x(O_1), 42 + x(O_1), 2) → list1bars
  11. Sequence(Text[Element[list1, n / 2], (n - 1, Element[list1, n / 2] + l1(0))], n, 2 + x(O_1), 42 + x(O_1), 2) → list1barstext
  12. Sequence(Text[Element[list1sorted, n / 2], (n - 2, Element[list1sorted, n / 2] + l1(0))], n, 2 + x(O_1), 42 + x(O_1), 2) → list1sortedbarstext
  13. Sequence(Text[Element[list2, n / 2], (n - 1, Element[list2, n / 2])], n, 2, 42, 2) → list2barstext
  14. Sequence(Text[Element[list2sorted, n / 2], (n - 2, Element[list2sorted, n / 2])], n, 2, 42, 2) → list2sortedbarstext

AI Drawing Prompt Reference

Create histograms for test scores of 20 students from two classes, A and B, with two x-axes representing score ranges for each class and a y-axis showing the number of students in each range. Use the histograms to display the score distribution for each class and label the median for each score range.
