Warming up in the cold

While walking to class i noticed that students wore beanies, baseball caps and their hoodies to keep warm, some didn't wear anything. While I was on my break i sat in the cub in looked out into Terrell Mall and counted how many students walked by wearing one of the three options or nothing at all. The results were: 64 wore beanies, 85 wore their hoodies, 190 were not wearing anything and 27 wore baseball caps.

This is a 1 to 5 ratio of the results. Green is beanies, brown is hoodies, orange is baseball caps and blue is wearing nothing.
