For example, in reference to our situation above, a patient's age may provide insight about a patient's survival time, however another explanatory variable, such as treatment plan, may provide a more accurate explanation for the accumulated data.Chambers 20th Century Dictionary (0.00 / 0 votes) Rate this definition: In Maths, a variable is an alphabet or term that represents an unknown number or unknown value or unknown quantity.
