Question

The school newspaper surveyed 100 commuter students and asked two questions. First, students were asked how many courses they were currently enrolled in. Second, the commuter students were asked to estimate how long it took them to drive to campus. Considering these two variables, number of courses would best be considered a ____________ variable and drive time would be considered a ______________ variable.
a) continuous, discrete
b) continuous, continuous
c) discrete, discrete
d) discrete, continuous

Answer 1

Answer: Option (D)

Explanation:

A variable tends to be either continuous or discrete. If the variable tends to have two significant real values so that it tends to take on real values in between them, then variable is considered to be continuous. If it tends to take on significant value so that there is non-infinitesimal gap on either side of it with no values it can take, then that variable is considered to be discrete.
