DEFINITIONS
Discrete data are restricted to defined separated values with a finite or countable number of different possible values, for example integers or counts.
Continuous data are not restricted to defined separate values, but can occupy any value over a continuous range, for example decimal, rational or real numbers.
SOLUTION
Y=number correct on a recent multiple choice test
Let the test contain n multiple choice questions.
Y can then only take on integer values from 0 to n.
Since there are a finite number of possible values for Y, the random variable is discrete.
Result:
Discrete.
