Quizplus · Accepted Answer

A continuous numerical variable is a variable that can take on any value within a certain range. Options A, B, and D are not continuous numerical variables since eye color and the number of employees are discrete variables, and the number of gallons sold is a discrete numerical variable (it can only take on certain values). The amount of milk produced by a cow in one 24-hour period, however, can be any value within a certain range, and is therefore a continuous numerical variable.
