To describe the interval data the descriptive statistics and histograms were used (Anderson, Sweeney, and Williams 98-150). The results of data processing about age, miles from home and other interval data are the following. The minimal age in the class is 19 years. The maximal age is 51 years. The average age is 26.78 years. However, the histogram shows that the most of classmates are at the age 21-23 years. The second biggest age group is 25-27 years. The age of the classmates is not normally distributed. It is positively skewed because the biggest group of respondents has the age below the average age.
The minimal distance from home to class one way is 1 mile. The maximal value of this variable is 50 miles. The average distance from home to the class is 19.78 miles.

There are two big groups of persons: classmates that live about 13 miles from the class and classmates that live about 19 miles from the class. The histogram for this variable is also positively skewed.
