This example demonstrates how to calculate the mean, standard deviation, 5-number summary, and interquartile range (IQR) using GeoGebra. Key mathematical concepts include arithmetic mean, median, and standard deviation. Commands such as Random, Sequence, Sum, Append, SampleSD, Mean, DotPlot, and BoxPlot are used to visually represent the data distribution. Suitable for middle school and above students or teachers.

GeoGebra Commands & Parameters

  1. Random(4, 7) → number
  2. Sequence(Random[3, 10] + a - a, a, 1, number - 1) → list1
  3. Sum(list1) → a
  4. Append(list1, sum - a) → list2
  5. SampleSD(list2) → b
  6. Mean(list2) → c
  7. DotPlot(list2) → list3
  8. BoxPlot(4, 0.5, list2) → d
  9. TableText({Sort[list2]}, "c|_") → text1
