Discrete Variable


Labid Khandaker


"Variables that can only take on a finite number of values are called "discrete variables." All qualitative variables are discrete. Some quantitative variables are discrete, such as performance rated as 1,2,3,4, or 5, or temperature rounded to the nearest degree. Sometimes, a variable that takes on enough discrete values can be considered to be continuous for practical purposes. One example is time to the nearest millisecond."

Discrete variables can be numbers that have a specific number of values. All qualitative variables are discrete, but there some quantitative variables that can be considered discrete due to their analytic structure such as "performance ratings."
