## MET 2920 Statistics

This is a basic statistics course that is included as a mandatory part of the bachelor programs in business administration subjects. The course provides an introduction to statistical thinking including basic probability theory, some statistical methods and elementary use of statistical data tools in order to be able to effectively process and analyze data. Use of statistical software is an important element of the course.

During the course, students will:

- Acquire a broad knowledge of the central statistical terms and understand how statistical analysis takes place from collection of data, via descriptive analysis to generalization to the population.
- Acquire knowledge within basic probability theory, including knowledge of certain probability distributions and the central limit theorem and why this knowledge is necessary to justify the use of various statistical methods to analyze data.
- Acquire knowledge of various statistical methods for analyzing data. Finally, the student will acquire knowledge of the elementary use of statistical data tools and understand that the use of statistical data tools is necessary to be able to effectively process and analyze data.

It is a goal that the course will enable the students to plan and carry out investigations using the most commonly used statistical methods. Students should be able to interpret analysis results from, for example, reports or computer printouts. After completing the course, students should be familiar with being able to use computer tools to process and analyze data.

- The students' ability for analytical thinking and an ability to reflect on results and calculations should be strengthened by completing the course.
- To understand that statistical methods can easily be misused.
- Taking anonymity and privacy into account when collecting data.
- To know that there are other branches within the statistics subject, such as econometrics and machine learning.

- Collection of data. Variables and measurementlevel.
- Descriptive statistics: Central measures, dispersion measures, covariation measures and graphical representations.
- Combinatorics and probability calculus. Conditional probability.
- Random variables. Expectation, variance and covariance.
- Central probability distributions with emphasis on the indicator distribution, binomial distribution, the normal distribution and the t-distribution. We are also considering a joint distribution for two discrete random variables.
- Estimators and estimation. Sampling distributions and the central limit theorem. Confidence intervals.
- Hypothesis tests for, among other things, average, proportion, comparison of averages in two groups, comparison of proportions in two groups, chi-square test for probabilities, chi-square test for covariation between categorical variables.
- Simple linear regression including inference (confidence intervals and hypothesis tests for the regression parameters).
- Active use of statistical software.

The course is carried out with 54 course hours which will consist of ordinary lectures where the syllabus is reviewed and problem solving (including problems which must be solved with computer tools). The software R is integrated into the teaching and the students will, through task solving, also actively process and analyze data using statistical software on their own.

Solving problems will be a central part of the joint lectures where the students are presented with tasks in the lecture and receive feedback by solving, reviewing and discussing these.

For each theme, a work program will be drawn up with literature references and task sets. The student must acquire the material in the literature reference and solve the tasks.

Computer tools are used in the subject. The tool will be R or other suitable software. The software R is free to download and does not require a license.

There are compulsory work requirements in the course where 3 out of 5 work requirements must be passed in order to sit for the exam.The final exam will be based on the students having solved the tasks and coursework requirements in the course.

__E-Learning__

Where the course is delivered as an online course, the lecturer will, in collaboration with the study administration, arrange an appropriate combination of digital learning resources and activities. These activities will correspond to the stated number of teaching hours delivered on campus. Online students are also offered a study guide that will provide an overview of the course and contribute to course progression. The total time students are expected to spend completing the course also applies to online studies.

__Re-sit examiniation__

Students who do not get the work requirement approved in the course are not allowed to take the exam. This means that they must take the entire course again when completing it later.

Students who do not pass the written exam or who wish to improve their grade can take a new continuation exam when the exam is completed later.

Higher Education Entrance Qualification

**Disclaimer**

Deviations in teaching and exams may occur if external conditions or unforeseen events call for this.

No specific prerequisites are required.

Mandatory coursework | Courseworks given | Courseworks required | Comment coursework |
---|---|---|---|

Mandatory | 5 | 3 | Throughout the semester, 5 compulsory coursework requirements will be given where the use of software is central. These must be answered in Itslearning. Each test is assessed approved or not approved. You are given the opportunity to take the test again if it is not passed on the first attempt. It is mandatory that the student has passed at least 3 of these 5 tests in order to sit for the exam. |
