From the point of view of mathematical statistics, there are two types of variables: discrete and continuous "random variables". :

*Discreet*Random variables have either a finite number or a countably infinite number of characteristics. The set of natural numbers is sufficient to name their characteristics. Depending on the number of manifestations, one also speaks of*dichotomous*(2),*trichotomes*(3),*polytomes*(finite number ) or from*Counting variables*(infinite number of expressions).- At
*continuous*Random variable is between two values also every intermediate value in the interval is possible, no matter how small this interval is. To name their characteristics, the set of rational numbers is necessary (e.g. decimal fractions with an infinite number of decimal places).

*Coincidence*variable). This distinction is important for applied statistics because mathematical statistics have developed different "distribution models" for discrete and continuous random variables that can be used for the statistical analysis of real phenomena. It is obvious, however, that these (theoretical) models cannot simply be transferred to real phenomena.
