...plays a role in certain areas where the recidivism rates are increasing. Lastly we will discuss several implications that could possibly reduce these rates. Introduction: A criminal career is a sequence of offenses during a period of an individual’s life. This repetitive criminal behavior is called recidivism, and indicates the proportion that becomes involved in criminal behavior, at what age criminal behaviors begins, how long the criminal career lasts and the number of offenses typically committed during the course of the career (Farrington, 1992) Also defined as an estimate of the percentage of released prisoner who commit another offense. There are three different measures of recidivism according to the Bureau of Justice Statistics. These are rearrests, reconviction, and reincarceration. Rearrests is described as any arrest that was reported to state identification bureau after release from a correctional bureau after release from a correctional institute. Reconviction can be referred to as a conviction on at least one charge after the release date. Reincarceration refers to any return to prison or any admission to a local jail with a new offense. The Problem: Recidivism is associated with increases in crime, homelessness, and family destabilization. In many cases, high recidivism results to failure to provide useful rehabilitation for offenders. Recidivism rates in urban centers tend to be higher than In rural areas. Also some factors we must......

...This paper will explain what statistics are. Statistics are used in so many ways, including business. This paper will thoroughly defining statistics, the types and levels of statistics, the role of statistics in a business and examples of how statistics may be used. The most common definition for statistics would be the collection of numerical data. Examples of numerical data could be the percentage of how many African-Americans passed, dropped out or failed out of high school in Vallejo, CA in 2013. Another would be how many slam dunks did LeBron James have last year or asking how many assist did LeBron James average last season; would give you numerical data. In this coarse, statistics is described as the science of collecting, organizing, presenting, analyzing, and interpreting data to assist in making more effective decisions. Statistics are usually divided into two catagories, descriptive and inferential statistics. Discriptive statistics are the methods of organizing, summarizing and presenting data in an informative way. Inferential statistics (also known as statistical inference) are the methods used to estimate a property of a population on the basis of a sample. There are two variables/attributes involved in statistics, qualitative and quantitative. Qualitative variables are when the characteristics being studied are categorical or nonnumeric. Quantitative variables are when a variable is studied and the study describes how much or how many. There are four......

...The article I chose suggests that Roman Catholics in the United States hope that the next pope could be younger and lead the church in a more liberal way regarding issues, such as birth control and same-sex marriage. The statistics is based on the latest New York Times/CBS News telephone poll conducted on landlines and cellphones from February 23 to 27 with 1,585 adults nationwide. Three-fourths of interviewers thought Pope Benedict should step down because he did a bad job dealing with sexual abuse. The poll suggested that many American Catholics are not confident about the church’s hierarchy since the bishops and cardinals do not understand their needs. The sample of telephone poll was randomly selected to ensure that each region of the country has almost same share of all telephone numbers, so it seems justified geographically. However, there is uncertainty in the survey because the margin of sampling error is plus or minus 4% for the 580 Catholics. An effective way to reduce the margin of error is to increase the sample size. There is also nonresponse error in the survey because some people do not answer calls from strangers, or refuse to answer the poll. In addition, due to selection bias, the opinions of those who agreed to be interviewed only reflect a certain part of the population. The article did well in analyzing from a series of data, mainly on the percentage of sample size. For example, the poll showed that 40 percent thought the pope is......

...1. Introduction Poverty, which is measured by the household income lower than poverty line has been identified as the dependent variable in this project. It is important to know which elements are associated with poverty. The purpose of this paper is to evaluate the key determinants of American household poverty in 1980. The four possible determinants will be analyzed in this project, the average numbers of every family (FAMSIZE), URB is the percent of people live in urban, UR is the level of people have no job over 16 years and the median family income in US dollars (INCOME). Descriptive statistics, correlation and regression will be used in this project. 2. Descriptive statistics Variable | Mean | Median | Mode | VAR | STDEV | URB | 58.76034483 | 66.15 | 0 | 1012.828049 | 31.82495953 | FAMSIZE | 3.140172414 | 3.135 | 2.93 | 0.033377163 | 0.182694178 | UR | 9.293103448 | 8.95 | 5.8 | 10.92696915 | 3.30559664 | INCOME | 19240.43103 | 18512 | N/A | 10889936.04 | 329.990309 | POV | 9.120689655 | 9.05 | 8.8 | 6.230792498 | 2.496155544 | 3.

...determine if the data are distributed normally. The Histogram below as well as the Descriptive Statistics (Appendix 1, Table 1b) show that the data distribution is leptokurtic (kurtosis is 2,021) and negatively skewed (skewness -,240). We can determine several outliers (Appendix 1, Table 1c, Table 1d) with extreme ratios. In cases #46 and #178 JSL is more than the highest option provided in the questionnaire. That could be a mistake in data entering or the respondent wanted to emphasise his/her satisfaction level. These cases were delisted. Cases with “0” responses are to be excluded from the further analysis as irrelevant data too. After the data revision there are 194 cases left in the dataset. Although the distribution is still negativeley skewed we may observe the distribution is closer to normal in terms of kurtosis. (Appendix 2, Picture 1a, Table 1c). We checked the significance of non normal distribution by comparing the numeric value of kurtosis with twice the Std. Error of kurtosis. Looking at the range from minus twice the Std.Error of kurtosis to plus twice the Std.Error of kurtosis, we see that the kurtosis value falls within this range. Thus the non normal distribution is considered to be insignificant. The JSL variable was also tested for the the distrubution normality depending on “Branch” and “Work Exp” variables. (Appendix, Histogram). Descriptive statistics of the subsamples shows that the skewness and kurtosis is acceptable , no outliers were......

...4. A psychologist interested in political behavior measured the square footage of the desks in the official office for four U.S. governors and of four chief executive officers (CEOs) of major U.S. corporations. The figures for the governors were 44, 36, 52, and 40 square feet. The figures for the CEOs were 32, 60, 48, 36 square feet. a. Figure the means and standard deviations for the governors and CEOs. b. Explain, to a person who has never had a course in statistics, what you have done. c. Note the ways in which the means and standard deviations differ, and speculate on the possible meaning of these differences, presuming that they are representative of U.S. governors and large corporations’ CEOs in general. 5. Radel and colleagues (2011) conducted a study of how feeling overly controlled makes you desire—even unconsciously—more freedom. In their study, 52 Canadian undergraduates played a video game in a laboratory and were randomly assigned to either: a. an automony deprivation condition, in which they were told to follow instructions precisely, constantly given instructions over a loudspeaker, and carefully observed on everything they did. b. a neutral condition, which was much more laid back. After this activity, they were asked to do a “lexical decision task” (a standard approach for measuring unconscious responses) in which they were shown a series of words and nonwords in random order and had to press “C” if it was a real word or “N” if not.
