The distribution of a quantitative variable is often modeled with a probability distribution. There is a wide range of mathematical probability models that are available for modeling the distribution of a quantitative variable; however, the particular probability model that is best used to model the distribution of a quantitative variable will depend on whether the variable of interest is discrete or continuous, the distribution of the variable, and any theoretical conditions or assumptions made about the population being modeled. Two of the most commonly used probability models in biomedical research are the Binomial Probability Model, which is associated with a discrete counting variable, and the Normal Probability Model, which is often used to model the distribution of a continuous variable.
