  • BP4: Students are able to transmit information, ideas, problems and solutions to both specialist and non-specialist audiences.
  • GP01: A capacity for analysis and synthesis.
  • GP02: A capacity for organisation and planning.
  • GP03: Oral and written communication in their mother tongue.
  • GP05: Computer skills relevant to the field of study.
  • GP07: The capacity to solve problems.
  • GP14: Critical and self-critical skills.
  • GP17: A capacity for self-reliant learning.

Up

Specific proficiencies

  • SP03: To discern information and data relevant to their particular enterprise which a non-professional would be unable to recognise.
  • SP04: To analyse business management problems, applying professional criteria based on the use of technical instruments.

Learning outcomes

  

At the end of the semester students must be able to:

  • Know the possibilities Statistics offer to obtain high-quality information and be able to recognize those situations when statistical analyses are possible and necessary. Differentiate between opinions that can be empirically contrasted and those that cannot.
  • Understand statistical terminology.
  • Know how to set out an economic problem using statistical terminology. Evaluate properly the difficulties to be overcome in each situation, recognize their limitations and resources.
  • Apply Inferential Statistics to problems arising from an economic environment.
  • Interpret outcomes and provide conclusions drawn from analyses relating them to the environment data come from.
  • Interpret and be able to question reports.
  • Develop attitudes favouring the understanding of new statistical procedures that can be useful in other subjects or along the professional career.

Methodology

 

Learning Activities:

Lectures A-1

Practice sessions A-2

Individual or teamwork projects or problem solving A-3

Individual or small group tutorials A-4

Individual work A-5

Exam A-6

Self-evaluation  A-7

Lectures will be devoted to introduce the subject basic contents that will be illustrated with practical activities to help students to develop individual-study habits. Lectures and practice session 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.

Evaluation

 

Learning outcomes Evaluation Weight (%) Recoverable
Understand the most usual random variables and probability distributions, their properties and those assumptions that make possible to approximate them to the Normal distribution. Understand the differences between population and sample, the main sampling distributions and their applications and those notions arising in Inferential Statistics. Obtain and interpret a confidence interval. Determine the needed sample size to reach required error objectives. Apply the appropriate test for a given problem. Evaluate the quality of survey reports published by the media. In-term tests 30 % No
Apply the appropriate test for a given problem. Interpret outcomes provided by statistical software.All the previous. Final exam 70% Yes

 

Continuous evaluation amounts up to 30% of the final mark.  The continuous evaluation 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. Continuous evaluation activities are not recoverable.

The remaining 70% of the final mark corresponds to the final exam. The final exam will be a written exam about the different theoretical and practical contents of the subject. The final exam may include problem solving, theoretical test-type or essay-type questions or designing how to solve an economic problem using statistical tools.

Contents

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.
