Fig. 5From: The Ontology of Biological and Clinical Statistics (OBCS) for standardized and reproducible statistical analysisOBCS modeling of statistical terms related to normal distribution. The normal (or Gaussian) distribution is a continuous probability distribution of a numerical data set that follows the normal distribution probability density function. The formula of the density function is at the bottom of the figure and included in OBCS as a ‘mathematical formula’ annotation. A normal distribution transformation is able to transform a data set to normally distributed data setBack to article page
