Business Statistics

Module name (EN):
Name of module in study programme. It should be precise and clear.
Business Statistics
Degree programme:
Study Programme with validity of corresponding study regulations containing this module.
International Business, Bachelor, ASPO 01.10.2020
Module code: IBB-230
The exam administration creates a SAP-Submodule-No for every exam type in every module. The SAP-Submodule-No is equal for the same module in different study programs.
Hours per semester week / Teaching method:
The count of hours per week is a combination of lecture (V for German Vorlesung), exercise (U for Übung), practice (P) oder project (PA). For example a course of the form 2V+2U has 2 hours of lecture and 2 hours of exercise per week.
6VU (6 hours per week)
ECTS credits:
European Credit Transfer System. Points for successful completion of a course. Each ECTS point represents a workload of 30 hours.
Semester: 2
Mandatory course: yes
Language of instruction:
Written exam (90 minutes / can be repeated semesterly)

[updated 25.11.2019]
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

IBB-230 (P420-0232) International Business, Bachelor, ASPO 01.10.2020 , semester 2, mandatory course
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
90 class hours (= 67.5 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 82.5 hours available for class preparation and follow-up work and exam preparation.

Learning outcomes:
After successfully completing this module, students will be able:
- to explain basic concepts of descriptive statistics for univariate and bivariate data analysis,
- to select appropriate methods for statistical data analysis and apply them in the context of business applications,
- to create visual representations of data,
- to analyze, quantify and interpret relationships between two variables,
- to describe and model random phenomena using concepts of probability theory,
- to explain basic probability rules and apply them to exemplary business statistical problems,  
- to calculate and interpret probabilities,  
- to apply special discrete and continuous probability distributions to business applications (e. g. binomial and normal distributions),
- to interpret and communicate the results obtained from a statistical analysis.

- Simple linear regression
Probability Theory:
- Definition of probability and basic concepts
- Fundamentals of set theory
- Empirical interpretation of probabilities (Laplace probability, statistical probability, subjective probability)

Teaching methods/Media:
Lectures supported by slides (projector) and blackboard (theory and example calculations). The lectures will be supplemented by exercises and tutorials. In order to support independent work, multiple exercise sheets covering the whole range of topics in this module will be provided. Solutions will be discussed with the students in the tutorials. Both the lecture notes and the exercise sheets will be available to students in electronic form.
