Read the article "Chicago falls out of 1st in murders" by David Heinzman from the Chicago Tribune, Jan. 1, 2003.  Then answer the following questions in your Word document. a. Does the headline "Chicago falls out of 1st in murders" refer to an absolute quantity or a relative quantity?  In other words, did Chicago fall out of first in absolute terms or in relative terms?  Briefly explain. It dropped out of first in absolute terms – pure number of homicides. This is mentioned in the second paragraph. It is still #1 with regards to homicide rate, a relative quantity. This is noted in the graph at the top. b. Let us look more carefully at the complete 2001 data.
