APPLIED BUSINESS STATISTICS
Obiettivi formativi
By the end of this course, students will be able to:
1. Understand and apply basic statistical concepts and principles to business problems.
2. Exploit regression analysis to analyze and interpret data in a business context.
3. Understand, use and interpret simple, multiple, and logistic regression.
Use the Python programming language to perform data analysis.
Risultati di apprendimento attesi
Understand the basic principles of applied business statistics and how they are used to make decisions in a variety of business settings.
Apply techniques of regression analysis to quantify the relationships between variables and make predictions based on data.
Apply logistic regression analysis to make predictions based on binary outcomes, such as yes/no decisions.
Understand the principles of clustering and principle component analysis.
Develop proficiency in using Python or other statistical software packages to analyze and interpret data.
Communicate effectively about statistical analyses and their results, both in writing and in oral presentations.
Think statistically.
By the end of the course, students should be able to use these techniques to analyze real-world data, draw appropriate conclusions, and communicate their findings effectively to others.
