  * The coefficient of variation (CV) is a normalized measure of dispersion of a probability distribution or frequency distribution.
  * The correlation coefficient (Pearson's r) is a measure of the linear correlation (dependence) between two variables.
  
  ## Science
  
  * In physics, a physical coefficient is an important number that characterizes some physical property of an object.
  * In chemistry, a stoichiometric coefficient is a number placed in front of a term in a chemical equation to indicate how many molecules (or atoms) take part in the reaction.
