Sit down somewhere where there are lots of people. Now categorize the people according to gender and hair color. Start with the males: Observe at least 20 and keep track of how many have hair that is in one of the following categories: black, brown, blonde, red, gray and other.Now do the females – again at least 20. In your write-up be sure to include your raw date as well as address the following questions: Do we expect male hair color to be generally distributed the same as female hair color? Why? Do we expect this data to vary depending upon the age of those we are observing? Why? If you wanted to measure what fraction of the population had each hair color what kinds of things would you have to take into account to do it well?
