Module: Statistics. Subject matter: Statistics II.
At the end of the semester students must be able to:
|Learning outcomes||Contents||Formative activities||Evaluation activities|
|Understand the most usual random variables and probability distributions, their properties and those assumptions that make possible to approximate them to the Normal distribution.||Chapters 1 and 2||Lectures and Practice sessions||In-term tests with and without using computer|
|Understand the differences between population and sample. Understand the main sampling distributions and their applications.||Chapter 3||Lectures and Practice sessions||In-term tests|
|Understand those notions arising in Inferential Statistics. Determine the needed sample size to reach required error objectives. Obtain and interpret a confidence interval. Apply the appropriate test for a given problem. Evaluate the quality of the survey reports published by the media. Interpret outcomes provided by statistical software.||Chapters 4, 5 and 6||Lectures and Practice sessions||In-term tests with and without using computer|
Practice sessions A-2
Individual or teamwork projects or problem-solving A-3
Individual or small group tutorials A-4
Individual work A-5
Lectures will be devoted to introducing the subject basic contents that will be illustrated with practical activities to help students to develop individual-study habits. Lectures and practice sessions will be alternated for all chapters.
Practice sessions will have two different approaches. Either they will consist of in-class problem-solving sessions of some proposed exercises by the professor or the students or they will consist of practice sessions with computers so that students will be required to use some statistical software as a tool to solve problems and practical cases. Lesson notes, as well as any other teaching material, will be available in MiAulario.

The evaluation method may include activities such as practice sessions, in-terms tests made with or without a computer, problem-solving based on computer-obtained outputs, and attendance to office hours.
The final exam will include questions about theoretical and practical topics studied in the course. These questions may consist of problem-solving questions, test-type questions, and/or solving economic problems using statistical tools.
The makeup exam will contain questions about theoretical and practical topics studied in the course. This exam might allow students to retake the continuous assessment.
The aim of this subject is that students learn:
- to consider an economic problem in statistical terms,
- to solve manually and by means of the statistical program R-Commander,
- to correctly interpret the results,
- to elaborate study reports.
This course is devoted to study:
- The main distributions of probability
- Statistical inference.
