While out on a five kilometer run on Wednesday evening I kept track of the make of the cars using a scrap pad of paper and a pen. I recorded each manufacturer for each car I saw on the road during my 41 minute run. During the run I made hash marks |||| next to manufacturer names. When I returned home I tallied up the counts from the run and made the following table:

Manufacturer	Frequency	Relative Freq
Toyota	90	30%
Nissan	51	17%
Mazda	42	14%
Honda	36	12%
Mitsubishi	32	11%
Suzuki	14	5%
Hyundai	12	4%
Ford	7	2%
Kia	6	2%
Isuzu	5	2%
BMW	2	1%
Daihatsu	1	0%
AMC Jeep	1	0%
Mercedes Benz	1	0%
300	1
