Double binning. The students in a statistics class conduct a transportation survey of students in their high school.

Among other data, they record the age and mode of transportation between home and school for each student.

The following table gives some of the data that were collected. For age: 1 = 14 years, 2 = 15 years, 3 = 16 years, 4 = 17 years, 5 = 18 years. For transportation: 1 = walk, 2 = school bus, 3 = public bus, 4 = drive, 5 = other.

a. Classify the two variables, age and transportation, as qualitative or quantitative, and give the level of measurement for each.

b. In order to be analyzed or displayed, the data must be binned with respect to both variables. Count the number of students in each of the 25 age/transportation categories and fill in the blank cells in the following table
