This example demonstrates the modification of a linear regression and correlation worksheet for public display. Key mathematical concepts include linear regression, correlation coefficient, and standard deviation. Using GeoGebra commands such as Point, PMCC, and FitLineY, the relationship between data points is visually illustrated. Suitable for middle school math education or data analysis presentations.

GeoGebra Commands & Parameters

  1. Point(Line[(1, 0), (1, 2)]) → data_1
  2. Point(Line[(2, 0), (2, 2)]) → data_2
  3. Point(Line[(3, 0), (3, 2)]) → data_3
  4. Point(Line[(4, 0), (4, 2)]) → data_4
  5. Point(Line[(5, 0), (5, 2)]) → data_5
  6. Point(Line[(6, 0), (6, 2)]) → data_6
  7. Point(Line[(7, 0), (7, 2)]) → data_7
  8. Point(Line[(8, 0), (8, 2)]) → data8
  9. Point(Line[(9, 0), (9, 2)]) → data_9
  10. Point(Line[(10, 0), (10, 2)]) → data_10
  11. PMCC({data_1, data_2, data_3, data_4, data_5, data_6, data_7, data8, data_9, data_10}) → r
  12. FitLineY({data_1, data_2, data_3, data_4, data_5, data_6, data_7, data8, data_9, data_10}) → Fit
  13. Point(xAxis) → K
  14. OrthogonalLine(K, xAxis) → a
  15. Intersect(a, Fit) → Projection

AI Drawing Prompt Reference

Draw a scatter plot with 10 data points on a horizontal line y=2, with x-coordinates from 1 to 10. Calculate the correlation coefficient r for these points and fit a line Fit through them. Draw a vertical line K on the x-axis, then draw a line a perpendicular to K, and finally find the intersection point Projection of line a and line Fit.
