occurs. In order to figure out what factor has the strongest relationship with crime occurrence. Out of all the factors, substance abuse had the strongest relationship with crime. As foretold in a previous section, 60% of individuals that are arrested test positive for either drugs or alcohol. Also, alcohol and drugs are implicated in an estimated 80% of offenses leading to incarceration in the United States (Wilcox, 2015). In addition, the findings of this proposal support all the hypotheses except

obstacles in survey studies is often eliciting responses from surveyed individuals. As we have seen throughout this semester, larger sample sizes are beneficial to statistical analyses, as increasing the sample size can increase the power of a hypothesis test, reduce the sampling variability in a sample, and meet the baseline number of collected ‘observations’ that are needed to perform specific analyses. This is not to say that larger sample sizes are unequivocally better; a truly random, yet representative

Answer to question 1: As given, it is well-known that Detroit has gone through decades of economic and social decay and has one of the highest crime rates in the country. Meanwhile, Boston is home to some of the top universities and medical schools in the world and has one of the lowest crime rates. In order to investigate the above information, three socio economic characteristics have been chosen here. They are median household income, per capita income and individual below poverty line. When

Danielle Kearns-Sixsmith Professor Keri Heitner RES 723 University of Phoenix December 23, 2014 Learner IQ and Media Preference The purpose of this study is to examine if a correlation exists between learners ' IQ and instructional media preference. A sample of 165 students who were high school freshmen and sophomores, ranging in age from 14-16 years, and were enrolled in a college preparatory social studies course in a small mid-Atlantic private school were invited to participate

analysis which will facilitate with rejection or acceptance of the working hypothesis. Throughout the duration of the research multiple tests were utilized, including a Chi-Square test, which analyzed levels of support for marijuana legalization against first age as the independent variable and the against level of education as a control variable. The first test in which only the independent and dependent variable are accounted for contains 5397 respondents, for which a total of 2103 respondents

The chi-square test will also include the Cramer’s V test to see the strength of the relationships. Another addition to the analytic strategy is using crosstabs where it can determine both variables such as the mother who spanked or slapped their child at least once to the child applying

Chapter 13: Chi-Square Applications SHORT ANSWER 1. When samples of size n are drawn from a normal population, the chi-square distribution is the sampling distribution of = ____________________, where s2 and are the sample and population variances, respectively. ANS: PTS: 1 OBJ: Section 13.2 2. Find the chi-square value for each of the right-tail areas below, given that the degrees of freedom are 7: A) 0.95 ____________________ B) 0.01 ____________________ C) 0.025 ____________________

correlations among the constructs is to be compared with the Average variance extracted. If the square root of AVE (depicted along the diagonal) for each construct is significantly higher than the cross-correlations shown along the off diagonal in the following table 5.6. The Chi-square results of respondents opinion on reaction constructs based on gender is shown in
