  Sampling error is the difference between a result calculated from a sample and the corresponding value in the population or data generating process (DGP). Sampling error occurs because different random samples contain different observations. Even ...

• Sampling Variation

  Sampling variation is the natural tendency for different random samples from the same population or data generating process (DGP) to produce different results. Because each random sample contains different observations, sample statistics and model ...
