This example demonstrates the application of the least squares method for bivariate regression analysis. Key mathematical concepts include linear regression and least squares. Using GeoGebra commands such as Point, Circle, Line, and Polygon, a regression model is constructed. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Point(yAxis) → P
  2. Circle(P, rQ) → p
  3. Line(P, Q) → a
  4. Polygon(B, RB, 4) → poly1, bb, rb, d, e, E, F
  5. Polygon(A, RA, 4) → poly2, c, ra, g, h, G, H
  6. Polygon(C, RC, 4) → poly3, i, rc, k, j, I, J
  7. Polygon(MP, M, 4) → poly5, mp, m, r, o, N, O
  8. Segment(M, O) → q
  9. Segment(N, MP) → s
  10. Intersect(q, s) → PA
  11. Segment(K, L) → l
  12. Segment(R, D) → n
