This example demonstrates linear regression fitting and PMCC calculation using GeoGebra. Core concepts include linear regression, PMCC, mean calculation, residual analysis, and similar triangles. Constructed with commands like FitPoly, PMCC, Mean, ResidualPlot, involving objects such as L_1 to L_5, f, a, b_1, g, m, b, h, and axis limits. Ideal for high school mathematics teaching on data fitting and statistics.

GeoGebra Commands & Parameters

  1. FitPoly(L_3, 1) → f
  2. PMCC(L_3) → a
  3. Mean(L_2) → b_1
  4. ResidualPlot(L_3, f) → L_5
  5. ResidualPlot(L_3, h) → L_4
