Imagine you select a reliably large probability sample of office workers from one specific office building at Yonge St. and Finch Ave., to do a survey. One question asks how they travel to and from work. You want to examine these data by comparing different groups, in this case, office workers who are in executive/management positions, versus in administrative staff positions. You’ve arrived at the following results:

	Total Sample	Executive/Management	Administrative staff
Total (n)	286	144	142
Total %	100%	100%	100%
I use the TTC	116	32	84
	41%	23%	59%
I drive	84	62	22
	29%	43%	16%
I do both	72	42	30
	25%	29%	21%
I do neither	14	8	6
	5%	5%	4%
