Course Description:  This course is to introduce the basic research method and quantitative techniques for law enforcement. Its aim is  to prepare students to be familiar with the methodology in research and statistics so that they can be able to  evaluate critically as well as enable to design various quantitative and qualitative research projects on their own.  Through the course, students will learn various new terms and techniques for conducting theoretically based  research. In addition, students will learn and practice various quantitative techniques for the description and  evaluation of crime prevention measures. Examples may include the analysis of crime data, program evaluation,  and community surveys. It is expected for students to develop the skills of critical thinking about issues,  practices, and numbers in the criminal justice system.  Course Objectives:  The study of this course will enable students to:  ∙ Identify the basic steps in the research process;  ∙ Explain the different levels of measurement;  ∙ Understand and explain the descriptive statistics;  ∙ Understand the measures of central tendency and dispersion;  ∙ Understand the measures of statistical significance, strength, and direction of a relationship;  ∙ Understand and explain the inferential statistics;  ∙ Understand hypothesis tests; and  ∙ Practice and be familiar with SPSS software for data analysis;  Classroom Courtesy:  Students are expected to observe basic rules of classroom courtesy. While the class is in session, newspaper  reading, text messaging, phone checking, sleeping, and conversation with neighbors are UNACCEPTABLE. Cell  phone, iPad, and any other electronic device, including a laptop computer, must absolutely be turned off and put  away. If any student is detected to use them, he/she will be asked to leave the session. If it occurs twice or more,  a letter grade for the course will be B (as the highest) or lower grades. If it happens three times or more, he/she  will automatically fail the course. In addition, any “incivility” of verbal expression, statement, or behavior to  students or professor during a classroom session, office hour, or any academic-related setting must not be  tolerated. LEJA 303:1– Quantitative Techniques for LE, SPRING 2017 2  WesternOnline:  This course is a WesternOnline-enhanced course. This means that most handouts and outside readings, if any,  will be uploaded at http://westernonline.wiu.edu/. Any email communication should be done via WesternOnline  email. The class announcement, schedule change, and all other changes will be uploaded on WesternOnline and  announced in class in advance. If at any point you are having trouble getting onto Western Online, contact the  UCSS Helpdesk at (309) 298-2704.  Class Attendance Policy:  The course is very intense and focused. Attendance is mandatory, and a daily roll is taken. TWO very strict  attendance policies are applied to all students (NO EXCEPTION!!!). PLEASE read the following policies very  carefully.  (1) There are total 43 SESSIONS during this semester, except the final examination. Those who have five (5)  and more unexcused absences will have two (2) percentage points per absence to be deducted from the  final percentage points. For example, if you earn the 95 percentage scores at the end of the semester with  six (6) unexcused absences, the final scores for a letter grade of this course will be 91, being subtracted four  (4) points for two (2) unexcused absences.  (2) Those who absent fourteen (14) and more, including all excused and unexcused absences will  automatically fail this course.  (3) Students are responsible for informing in advance or in a timely manner of the reason for their absence.  An excused absence includes illness, bereavement, or religious observances. Just an email, verbal, or  telephone notice for the possible absence or after-the-fact report DOES NOT count as an excusable  absence! You MUST provide a proper documentation. (4) Any absence for earlier holiday observation is NOT an excused absence.  Therefore, it is your absolute responsibility to attend class, participate in order to fulfill course requirements, and  check the number of your absences. Any student who is tardy to class without cause, or leaves during classroom  session for an unexcused reason or prior notification, will be given an unexcused absence for that session. Your  professor will make the determination if the reason for an absence or tardiness is excusable or not.  Grading Policy:  This course is 300-level. Expectations are VERY high with two examinations, WorkNotes, exercises, individual/  team projects, SPSS Lab exercises, and class participation. All your scores from the “Activity” will be converted  into the “percentage point.” The grading criterion is presented below. All grades will be uploaded on  WesternOnline “gradebook” accordingly.   Student Evaluation

Examination:  There are two (2) examinations. The exams include material covered in the readings and in classroom  discussions/lectures. All materials covered in class are not necessarily in the readings. You are responsible for  the readings as well as information from the lectures. Since some students perform well in multiple-choice  questions, true-false answers, others on essays, and yet others on short answers, the exams in this course include LEJA 303:1– Quantitative Techniques for LE, SPRING 2017 3  a mixture of these testing techniques. On the essay section, you must write according to essay format, not  fragmented lists. The exams are not cumulative.  WorkNote:  Worknotes are designed to hold you accountable for daily/weekly readings and lectures. There are four (4) parts  of the WorkNotes according to the major sections of this course. The format of your WorkNote is mostly short answer questions. You have to answer them during classroom sessions or after the sessions. The WorkNote will  be collected after the session and be brought back in the following session. It is your responsibility to print  them out from WesternOnline and keep them to prepare the examinations later on. PLEASE do not do your  missed WorkNotes in class. There is no make-up or late submission for it.  Course Exercise and Quiz:  “Course Exercise” consists of several activities: (1) classroom exercise; (2) textbook exercise; (3) take-home  exercise; and (4) SPSS Lab exercise.  (1) The “classroom exercise” may include such activities as classroom discussion, classroom statistical  calculations, and classroom team project.  (2) The “textbook exercise” is to answer the “EXERCISES” questions. Each chapter has its section at the end.  Selected questions and sections will be assigned according to class lectures and discussions.  (3) The “take-home exercise” is to design to practice statistical techniques (i.e., to calculate averages,  standard deviation, etc.) with real datasets.  (4) The “SPSS Lab exercise” is to design to have hands-on practices of SPSS (Statistical Package for the Social  Sciences), a popular statistical software (available with the computers at Stipes 303 and Stipes Computer  Labs). The datasets and lab exercise guidelines will be either uploaded on WesternOnline or handed out  in class.  “Quiz” is designed to help you to review your weekly studies and exercises and to prepare the exams. There will  be several quizzes by each chapter and available in WesternOnline quiz format. Quizzes will be UNANNOUNCED  and administered in class. There is NO make-up quiz. Several course exercises and quizzes will be assigned  with 10 points per assignment. The sections and instructions for all exercises will be EITHER handed out in class  OR uploaded on WesternOnline in advance.  Statistics Project:  It is a team project to locate a statistical file mostly from the Interuniversity Consortium for Political and Social  Research (ICPSR; https://www.icpsr.umich.edu/icpsrweb/), which is a central repository of data collected by  social science researchers. All students must create an account in order to access the website to locate the file.  The purpose of this project is to find an original statistical data as a secondary data source, to identify the title  and goal of the study, to identify key variables, and to conduct statistical analyses, which will be covered in this  class. The final product is to prepare a statistical paper and to present it to the class. All detailed guidelines for  several steps will be uploaded on WesternOnline in advance.  Late Work and Make-Up Exam Policy:  All assignments are due before the session: not the middle; not the end; and not anytime after the session. There  are NO make-up exams without documented, verifiable doctor’s excuse or emergency the DAY of the exam (not  the day or week before). Further, you must notify me prior to the exam to explain your absence with the  documentation. If a make-up should be necessary, it will be comprised of essay questions ONLY. The missed  exam must be completed within one week of the scheduled date. Failure to take any examination may result in  the student earning a Letter Grade F. In addition, if you expect to have an excused absence, you HAVE TO have  the course requirement done in advance (e.g., test, quiz, exercise, etc.), NOT after the absent date. And NO LATE  SUBMISSION will be accepted absolutely!!  Student Rights and Responsibilities:  Please see http://www.wiu.edu/provost/student.phpLEJA 303:1– Quantitative Techniques for LE, SPRING 2017 4  Student Academic Integrity Policy:  The instructor will refer any findings of academic dishonesty (e.g., cheating and plagiarism) to university  administrative officials for disposition (http://www.wiu.edu/policies/acintegrity.php).  Students with Disabilities:  In accordance with University values and disability law, students with disabilities may request academic  accommodations where there are aspects of a course that result in barriers to inclusion or accurate assessment of  achievement. To file an official request for disability-related accommodations, please contact the Disability  Resource Center at 309-298-2512, disability@wiu.edu or in 143 Memorial Hall. Please notify the instructor as soon  as possible to ensure that this course is accessible to you in a timely manner.  Title IX Policy:  University values, Title IX, and other federal and state laws prohibit sex discrimination, including sexual  assault/misconduct, dating/domestic violence, and stalking. f you, or someone you know, has been the victim of  any of these offenses, we encourage you to report this to the Title IX Coordinator at 309-298-1977 or anonymously  online at http://www.wiu.edu/equal_opportunity_and_access/request_form/index.php. If you disclose an  incident to a faculty member, the faculty member must notify the Title IX Coordinator.
