A report in the journal Cancer suggests that women who take aspirin on a regular basis lower their risk of a certain kind of melanoma.2 Every woman who visits the Turtle Creek Medical Center in Dallas, Texas, during the next business day will be asked whether she regularly takes an aspirin. Let X be the number of women who take an aspirin daily. Is X discrete or continuous?

Solution

X is discrete, as it cannot take any value. It can only take integer values. [ANSWER, DISCRETE]

For example, there cannot be 3.45 women who take aspirin, but you can say 3 or 4 or 5 women take aspirin.
