Objectives

This course complements the statistical background initiated with Applied Statistics I. Specifically, we want that students in the end of this course:
1. Be able to conduct a quantitative exploratory analysis of data in order to explain criminal phenomena
2. Dominate the use of statistical techniques in social sciences and specifically in criminology.
3. Be able to explore quantitative associations between studied variables and to identify causality relationships.
4. Be able to work with statistical software packages (specially SPSS software)

Teaching methods and learning activities

Two types of classes: Theoretical and Laboratorial applied work
Theoretical concepts are presented and explained in theoretical classes. Afterwards, those concepts are applied in laboratorial work, trying to prepare students to be able to make their own research on criminology.

Software

PASW (ex-SPSS) version 17
Software de folhas de cálculo (e.g., Excel)

Eligibility for exams

In order to complete with success the course on Applied Statistics II, students must attend an written final exam (EF) and complete an (practical) written assignment (T), with a final weighted sum of at least ten points.

Calculation formula of final grade

Final classification = 0,75xEF + 0,25xT, where EF e T.
EF and T are classified individually in a range between zero and twenty points.

Examinations or Special Assignments

See previous note.

Special assessment (TE, DA, ...)

According to Main Regulation of the University and of the Criminology course.

Classification improvement

According to Regulations of the University and of the Criminology course.
In order to improve grades in this course, student must repeat a written final exam and/or written assignment.
