This example demonstrates the comparison between t distribution and normal distribution. Key mathematical concepts include types of distributions in probability and statistics. Using GeoGebra commands TDistribution, Normal, and IntegralBetween, the differences between t distribution and normal distribution under different degrees of freedom can be visually illustrated. Suitable for learners of statistics and probability theory.

GeoGebra Commands & Parameters

  1. TDistribution(df, x) → f
  2. Normal(0, 1, x) → g
  3. IntegralBetween(f, 0, (-StandardErrorsAboveMean), StandardErrorsAboveMean) → b
  4. IntegralBetween(g, 0, (-StandardErrorsAboveMean), StandardErrorsAboveMean) → c
