Learning outcome
Acquired knowledge

  • To see the relevance and use of statistics in marketing and economics
  • To think critically about the application of statistical methods
  • To understand the relation between the population and the sample at hand, and how it is affected by randomness
  • To be aware that statistical methods are based on assumptions that must be checked
  • To understand the underlying ideas behind estimation and hypothesis testing

Acquired skills
  • To be able to handle fractions, functions and graphs; and be able to read the mathematical notation that arises in statistical formulas
  • To know how to use statistical software to produce graphics and numbers; to be able to interpret output from such software
  • To be able to describe data with key statistics and graphical displays
  • To be able to calculate simple probabilities and confidence intervals
  • To know how to conduct tests of hypotheses for the mean and proportion in a population, or for the differences in mean in two populations
  • To be able to do a regression analysis and interpret the result

  • The student should also be aware that statistical methods may be easily misused and misinterpreted. It is important that the judgment required for statistical analysis is fair and just.

Learning process and workload
The course consists of 48 hours of lectures, including 10 hours of demonstration of statistical software. The problems studied in class and given as homework assignments will serve as a basis for the final examination.

Work requirement:
In the course of the semester 6 mandatory multiple-choice assignments will be given. These are submitted on It's Learning. Each assignment is assessed as either pass or fail. The student needs at least 4 passes in order to take the final exam.

Outline of workload for a student:
Use of hours
It's Learning assignments
Working with SAS JMP (or some statistical software)
Textbook study
Preparation for the examination

The e-learning platform It’s Learning is used by the e-learning centre to administrate the mandatory exercises, and make students able to communicate with each other and the lecturer. Module sessions are carried out at the beginning of the semester and before examinations. The e-learning students are also offered a study guide that is an educational guide to the syllabus.

    Coursework requirements
    The students must have passed four of the six multiplechoice tests in order to take the exam.

    A five hour individual written exam concludes the course.

    Examination code(s)
    MET 34311 Examination that accounts for 100 % of the grade in MET 3431 Statistics, 7,5 ECTS credits..

    Examination support materials
    All support materials and calculator TEXAS INSTRUMENTS BA II Plus™ are allowed.
    Examination support materials at written examiniations are explained under examination information in the student portal @BI. Please note use of calculator and dictionary.

    Re-sit examination
    A re-sit examination is offered every term.
    Students that have not passed five of the mandatory eight multiple-choice assignments must retake the exercises in connection with the next scheduled course and must pass five of the eight submitted multiple-choice assignments. Students that have not passed the written exam can retake the exam in the next semester.
