Homicide: Annotated Bibliography

The article that I chose to write about covers homicides that have taken place across Cincinnati's 53 neighborhoods for a 36-month period last year. The article was an interest of mine, because an old school friend’s father took the job as the police chief in Cincinnati recently. When I viewed the data that was presented in the article, the horizontal axis explained the number of homicides in a neighborhood. The vertical axis explained how many neighborhoods had each of these numbers; in the first column, 13 neighborhoods had zero homicides (Crowe, 1991). Most neighborhoods had few homicides, but there are a few neighborhoods in Cincinnati that have many homicides.

Often times, you will need to summarize a distribution. There are two basic descriptions of distributions: the average case and the variation. The average can be calculated three ways which are mean, median, and mode. The mean is the most common number of the averages (Rengert & Mattson & Henderson, 2001). The mean number of homicides in the Cincinnati neighborhoods is 3.7 homicides per neighborhood, which was determined by dividing the 198 killings in the 53 neighborhoods. The median is what divides the two cases into their individual, yet equal groups (Rengert & Mattson & Henderson, 2001). Half the Cincinnati neighborhoods have two or more homicides and half of the neighborhoods have two or less homicides. Lastly, the mode is the possessed value that is determined by the greatest number of existing cases. …show more content…
There are three common methods to calculate the spread of the homicides that are: range, inner quartile range, and standard deviation. The range is calculated by taking the lowest value from the highest value (Rengert & Mattson & Henderson, 2001). The range for Cincinnati homicides are 0 to
