Educational Goals

The general aim of the course is the understanding and knowledge of the operation of statistical inference with an emphasis on the development of statistical thinking and the ability to analyze quantitative and qualitative data. The application of techniques in the analysis and interpretation of the results of the economy and businesses in the context of both the Greek and the international economic environment, the trends and the demands of the interested parties in terms of the degree of comparability, is also a pursuit, as statistical methods find applications in almost all branches of human activity.

Upon successful completion of the course, students are expected to be able to:

• Use their knowledge and understand issues of generalization of conclusions.
• Perform case checks.
• Have the ability to apply regression methods.
• Use statistical calculus for the analyses.
• Evaluate and compose reports and analyzes that refer to financial management issues.
• Acquire the necessary skills to support the extroverted orientation of agencies and businesses and draw conclusions referring to the data set by using a (small) subset of it.

Students Evaluation

Theory
Written final exams that may include:

• Judgemental questions.
• Short answer questions.
• Comparative evaluation of theory elements.
• True/False and multiple choice Questions .
• Application exercises.

In each question, corresponding evaluation points are specified.
Optional assignment (Essay writing) corresponds to 40% of the final grade.
