Solved – the difference between “random noise” and “statistical noise”

noiseterminology

According to English wikipedia, there are Statistical noise and Random noise (e.g., white noise). However, I've never seen definitions of what statistical noise is. So, what is the difference if any? Does statistics have it's own noise or is it just an informal term, depending on the usage context?

In physical sciences, the statistical noise (error) is a random noise.

Here's how the statistical errors are defined in this deck by a DESY physicist:

Statistical errors are due to statistical uncertainties:

  • arise from stochastic fluctuations (random quantum processes),
  • are uncorrelated with previous measurements,
  • follow well-developed theory;
  • examples are finite statistics (Poisson distribution) and measurement resolution.

Here's how random errors are defined in IUPAC Gold Book:

Result of a measurement minus the mean that would result from an infinite number of measurements of the same measurand carried out under repeatability conditions.
