Under this method ##5## ##5.1## ##5.01## ##5.0000000000000000001## etc would all be distinct ages. If the discrete variable has many levels, then it may be best to treat it as a continuous variable. Think of it like this: If that number in the variable can keep counting, then its a continuous variable. quantitative. ). As opposed to discrete data like good or bad, off or on, etc., continuous data can be recorded at many different points (length, size, width, time, temperature, cost, etc. Discrete data can take on only integer values whereas continuous data can take on any value.
