This example demonstrates the construction of a histogram with equal widths, focusing on statistical concepts like frequency distribution and data visualization. The key steps involve using GeoGebra commands such as Polygon, CountIf, TableText, and Histogram to create the histogram. Suitable for middle school students learning statistics or high school students practicing data analysis.

GeoGebra Commands & Parameters

  1. Polygon(A, B, C, D) → poly1, a, b, c, d
  2. Polygon(A_1, B_1, C_1, D_1) → poly1_1, a_1, b_1, c_1, d_1
  3. Polygon(A_2, B_2, C_2, D_2) → poly1_2, a_2, b_2, c_2, d_2
  4. Polygon(A_3, B_3, C_3, D_3) → poly1_3, a_3, b_3, c_3, d_3
  5. Polygon(A_4, B_4, C_4, D_4) → poly1_4, a_4, b_4, c_4, d_4
  6. Polygon(A_5, B_5, C_5, D_5) → poly1_5, a_5, b_5, c_5, d_5
  7. Polygon(A_6, B_6, C_6, D_6) → poly1_6, a_6, b_6, c_6, d_6
  8. Polygon(A_7, B_7, C_7, D_7) → poly1_7, a_7, b_7, c_7, d_7
  9. Polygon(A_8, B_8, C_8, D_8) → poly1_8, a_8, b_8, c_8, d_8
  10. Polygon(A_9, B_9, C_9, D_9) → poly1_9, a_9, b_9, c_9, d_9
  11. Polygon(A_{10}, B_{10}, C_{10}, D_{10}) → poly1_{10}, a_{10}, b_{10}, c_{10}, d_{10}
  12. Polygon(A_{11}, B_{11}, C_{11}, D_{11}) → poly1_{11}, a_{11}, b_{11}, c_{11}, d_{11}
  13. CountIf(B5, list1) → C5
  14. CountIf(B6, list1) → C6
  15. CountIf(B7, list1) → C7
  16. CountIf(B8, list1) → C8
  17. CountIf(B9, list1) → C9
  18. TableText({{B4, C4}, {B5, C5}, {B6, C6}, {B7, C7}, {B8, C8}, {B9, C9}}, "|_") → text13
  19. Histogram({0, 1, 2, 3, 4, 5}, list1) → f

AI Drawing Prompt Reference

Create a histogram to show the frequency distribution of a set of data. First, draw 9 rectangles of equal width, each representing a data interval. Then, count the number of data points in each interval and label these counts above the corresponding rectangles. Finally, use these counts to generate a histogram that displays the frequency of each interval.
