Statistics paper - Essay Example ere chosen for discussion in this statistics paper from the works of Bennett (2004), Greenblatt (2002), Hiller, Knight, Rao and Simpson (2000), Makkai and Payne (2003), Niazi, Pervaiz, Minhas and Najam (2005), Wei, Makkai and McGregor (2003), and Young, Dembo and Henderson (2007). The Bennett (2004) study began in 1996 to ascertain the prevalence of drug usage among offenders in the United Kingdom, and to trace whatever links there are between drugs and crime in relation to arrestees. This study was patterned after the Drug Use Forecasting (DUF) program of the United States Department of Justice.

The proportion states the relationship of one part of a measure compared to a whole. In this study, proportion was oftentimes used to depict the picture of the size of the populations of arrestees testing positive for any of the eight substances in the aforementioned paragraph, such as â€Å" †¦ three out of four arrestees tested positive for at least one drug (including alcohol)† (p. 18). The median in this study describes the midpoint of the range where half of the data contained in the range falls

His lifes associations are not the beautiful girls, belief in God, honor, work, friendship or love for ones family. Instead, he believed in these elements as instruments to survival and diversions.

Krebs disillusionment of his hometown and people stems from his post at Belleau Wood, Soissons, the Shampagne, St. Mihiel and the Argonne, where the battles had been the most fierce and bloody. These battles have had a deep impact on Krebs yet he is reluctant to talk about them. This is partly because people in Kansas already "had heard too many atrocity stories to be thrilled by actualities" and partly because these experiences have more value to him than his audience. He has found lying to make himself heard by his hometown too demeaning, and hence have been unwilling to degrade his memory and experience of war. Instead, Krebs has assumed a secluded lifestyle so that he does not have to encounter such situations when he had to lie about his war experiences.
