That's not a right question.

IF (and only **if** ) orange juice could only be produced in exact gallon units, you could **count** the units, and it would be a discrete variable, like in the question: "How many gallons of OJ does a familiy buy every month" (provided they can't buy anything but whole gallons).

In all other cases the variable will be **continuous** , as you can drink or buy any amount of OJ, even half a liter.

Count => discrete

Measure => continuous
