continuous and discrete variables
Continuous variables
a continuous variable is one that can take on any values on the measurement scale under consideration. Examples of continuous variables are weight, height, income, age, etc.
We sometimes refer to a continuous variable as one that has underlying continuity. That is, there are no breaks in the possible values it can assume.
Discrete variables
As opposed to a continuous variable, a discrete variable can take on only designated values. For example, number of cars a household possessed. This variable can take on only integer value, that is 1, 2, 3 and son on. There can be no fractional value at any one time.
