Official Statistics on crime are often likened to the ¡§tip of an Iceberg¡¨. Critically assess this assertion in light of the ¡§dark figure¡¨ of crime and any new forms of data that can provide a clearer picture of the true extent of crime. Crime is continuously changing in its definition in people¡¦s perceptions with no complex classification being universally accepted. This forms the basis of the problems faced when attempting to count crime‚ who determines what crime is; the government of

Descriptive statistics is the discipline of quantitatively describing the main features of a collection of data.[1] Descriptive statistics are distinguished from inferential statistics (or inductive statistics)‚ in that descriptive statistics aim to summarize a sample‚ rather than use the data to learn about the population that the sample of data is thought to represent. This generally means that descriptive statistics‚ unlike inferential statistics‚ are not developed on the basis of probability

In Graph 1‚ each line of color represents a different level of pH added to the solution. When pH 9 was added‚ it produced the highest rate of reaction (the most oxygen was produced)‚ whereas when the more acidic pH 5 was added‚ the rate of reaction was much slower‚ and less efficient. The higher the oxygen evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal

A Synopsis of How to Lie with Statistics by Darrell Huff When most people hear or read a statistic‚ they quickly have to decide if the numbers listed are valid or invalid. It is usually assumed that the author of the statistic is knowledgeable in the field to which the statistic pertains. However‚ on many occasions‚ the statistic is false‚ due to the author’s wording. Darrell Huff’s novel How to Lie with Statistics is a manual that can help individuals catch these lies. The novel allows readers

Ilya Zaihrayeu http://www.dit.unitn.it/~ilya/os.htm Deadlock Prerequisites Deadlock can arise if four conditions hold simultaneously: Mutual exclusion: only one process at a time can use a resource. If another process requests that resource‚ the requesting process is delayed until the resource is released; Hold and wait: a process holding at least one resource is waiting to acquire additional resources

LINEWEAVER-BURK PLOT A graph of the double reciprocal equation is also called a Lineweaver-Burk‚ 1/Vo vs 1/[S]. The y intercept is 1/VMAX; the x-intercept is 1/ KM; and the slope is KM/VMAX. Lineweaver Burk graphs are particularly useful for analyzing how enzyme kinematics change in the presence of inhibitors‚ competitive‚ noncompetitive‚ or a mixture of the two. There are three reversible inhibitors: competitive
