Origin of normal distribution
WitrynaWhat is a normal distribution? Early statisticians noticed the same shape coming up over and over again in different distributions—so they named it the normal distribution. Normal distributions have the following features: symmetric bell shape mean and median are equal; both located at the center of the distribution \approx68\% ≈ 68% WitrynaOn average, the faults in the Southern Levant Basin are 6.3 km long, have an average throw of 120 m, and consistently strike NW-SE. Throw-depth plots, accompanied by thickness changes, indicate that the faults accumulated growth strata during the Late Burdigalian and are spatially and kinematically associated with a WSW-ESE-striking …

Gauss, a German mathematician who made significant advancements of statistical concepts. lavet boituvaIn statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.
