Employment Data Listed below is results from the National Health and Nutrition Examination.
1 3 3 2 1 1 1 7 9 1 1 1 4 4
These results indicate the working status of the person being surveyed, and the listed values represent these responses:
I = Working; 2 = with a job but not at work; 3 = Looking for work; 4 = Not working; 7 = Refused to answer; 9 = don't know. Does it make sense to calculate the mean of these numbers? Why or why not?
