Continuous Variable

---

A continuous variable is one for which, within the limits the variable ranges, any value is possible. For example, the variable "Time to solve an anagram problem" is continuous since it could take 2 minutes, 2.13 minutes etc. to finish a problem. The variable "Number of correct answers on a 100 point multiple-choice test" is not a continuous variable since it is not possible to get 54.12 problems correct. A variable that is not continuous is called "discrete".
