Norwegian**Introduction**

This is a basic course in statistics. Main themes are descriptive statistics and statistical inference. In addition some emphasis is placed on acquiring basic skills in mathematics.

**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

**Reflection**

- 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.

**Computer-based tools**

SAS JMP is used as a teaching tool.

**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 8 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 5 passes in order to take the final exam.

**E-learning**

In course delivery as online courses or evening classes, will lecturer, in collaboration with the Academic Services Network and evening studies, organize an appropriate combination of digital and class room teaching. Online students are also offered a study guide, which will help progression and overview. Total recommended amount of time for completion of the course also applies here.

**Coursework requirements**

The students must have passed five of the eight multiplechoice tests in order to take the exam.

**Examination**

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 + BI approved exam calculator. Examination support materials at written examinations are explained under examination information in the student portal @bi. Please note use of calculator and dictionary in the section on support materials (https://at.bi.no/EN/Pages/Exa_Hjelpemidler-til-eksamen.aspx).

**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.
