Still, one of the questions is asked of parents and students. It is, "Ideally, how far from home would you like the college you (your child) attend(s) to be? As you might expect, parents and students do not agree. Let's look at the frequency table along with the relative frequency table. Remember the relative frequency table should be used.

The reason we use the relative frequency is because the sample size is not similar (10,398 students compared to 3,750 parents). See the comparison below.
