Of the 22 students surveyed on miles with range of 68 the mean is 21.34, Median is 15, Mode is 2 and standard deviation is 3.87. By computing number of minutes’ drive to class, out of 22 student’s travelled with range of 65, mean is 33.86 which suggests most of students are living far from campus, median 32.5 and mode is 20 which suggest majority are living within 20 minutes’ drive. The standard deviation to data is 21.79. By computing number of meals eaten out per week, out of 22 students mean is 4.31 slightly higher than median and mode due to maximum variables 15 and 14, median is 2 and mode is 2 which reveals the fact that majority spends twice a week to eat out. The standard deviation of data is 4.22. By computing number of years of job experience, out of 22 students mean is 6.34 higher than median and mode due to two students have more than 20 years of work experience, median is 3 and mode is 1 which suggest majority students have only one year work experience. The standard deviation of data is 7.56.
