Study Notes

Gaussian Distribution

  • The Gaussian distribution is also known as the Normal Distribution or Bell Curve.
  • It is characterized by a symmetrical, bell-shaped curve with a single peak at the mean, and tapering gradually to infinity in both directions.

Central Limit Theorem (CLT)

  • The Central Limit Theorem describes how the distribution of random values will approach a Gaussian distribution as the number of values in a sum increases.
  • As the number of values in a sum rises, the distribution of the sum will tend towards a Gaussian distribution, even if the individual values are not normally distributed.

Gaussian Distribution Applications

  • The Gaussian distribution describes the distribution of continuous variables that are influenced by a large number of small, random factors, such as human heights, IQ scores, or errors in measurement.
