This example demonstrates the concept of arithmetic mean. By constructing the arithmetic mean of a sequence, students can visually understand the calculation method of arithmetic mean. It uses GeoGebra commands such as Sequence, Mean, and Segment, suitable for middle school and above students.

GeoGebra Commands & Parameters

  1. Sequence(Random[0, 6], i, 1, 5) → data
  2. Mean(data) → ans
  3. Sequence((i, data(i)), i, 1, 5) → ptList
  4. Sequence(Polygon[ptList(i), (i - 1, data(i)), (i - 1, 0), (i, 0)], i, 1, 5) → list1
  5. Segment(drag, (5, mean)) → f
