## MET 3431 Statistics

The course provides an introduction to statistical thinking. The student first learns how a sample can be collected and summarized, and how we use such summaries to interpret the data. Then we learn to generalize from the sample to the population. The student learns to construct confidence intervals and to perform hypothesis tests, and how these should be interpreted. The focus is on understanding concepts, and on interpreting results, with less focus on mathematical procedures. Through many examples from reality, the student should be able to see the relevance of and uses for statistics in marketing and economics.

During the course the students will:

- Acquire broad knowledge of the central statistical concepts and understand how statistical analysis takes place from data collection, through descriptive analysis to generalization to the population.

Examples of terms that should be explained are sample, population, observer, parameter, inference, margin of error, significance level and confidence level. - Knowledge of the limitations of statistical method.

After completing the course, students will be able to:

- Determine the target level of variables, and be able to perform descriptive analysis based on a sample, with appropriate center and scatter targets and appropriate graphs.
- Describe the covariance between two variables.
- Interpret results of descriptive analysis. Simple probabilities must be calculated.
- Be able to construct and interpret the most commonly used confidence intervals, and perform key hypothesis tests.
- Use statistical software and be able to interpret printing from the software.
- Present the results of the analyzes in an easy-to-understand language.

The student should 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.

- Collection of data
- Describing the sample at hand
- Probability
- Confidence intervals for mean and proportion
- Hypothesis tests for mean and proportion
- Correlation and regression
- Chi-square test

The course consists of 48 hours of lectures, including 4 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.

For each week there will be given a work program with literature references and assignments. In lectures and SAS JMP exercises, theory will be illustrated by using multiple data sets and associated tasks. The final exam will be based on that the student has solved all these tasks throughout the semester.

__E-learning__

In course delivery as online courses, lecturer will, in collaboration with the student administration, organize an appropriate course implementation, combining different learning activities and digital elements on the learning platform. Online students are also offered a study guide that will contribute to progression and overview. Total recommended time spent for completing the course also applies here.

__Re-sit examination__

Students that have not gotten approved the coursework requirements, must re-take the exercises during the next scheduled course.

Students that have not passed the written examination or who wish to improve their grade may re-take the examination in connection with the next scheduled examination.
