Normal distribution

This histogram sample shows the random sample of 100 observations from the normal distribution N(0,1). It was designed on the base of the Wikimedia Commons file: Histogram example.svg. [commons.wikimedia.org/wiki/File:Histogram_example.svg] "In probability theory, the normal (or Gaussian) distribution is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known." [Normal distribution. Wikipedia] The histogram example "Normal distribution" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Histograms solution from the Graphs and Charts area of ConceptDraw Solution Park.
