A flow variable is measured per unit of time, such as income or spending per year. A stock variable, on the other hand, is a quantity that is measured at a specific point in time, such as the amount of money in a bank account. Periodic variables refer to phenomena that occur regularly, such as seasonal changes. Dummy variables are used in statistical analysis to represent categorical variables, and controlled variables are variables that are held constant in an experiment.
