• Formulating the research questions, developement of a research design
• Sampling and data sources, sample selection, finding data for research projects.
• Regression analysis: multivariate regression, assumptions and properties, violation of assumptions and remedies.
• Factor analysis: model, extraction, rotation, interpretation.
• Scale construction and evaluation: reliability analysis and composite scores.
• Machine learning - Cluster analysis.
• Regression analysis revisited: regression analysis in combination with factor analysis and cluster analysis, binary response models.

• Become proficient use of AI as a tool for conducting research projects
• Select, clean and manage large and complex data sets to be used for applied research.
• Distinguish between different kinds of variables.
• Explain how variables can be used in standard statistical techniques.
• Explain linear regression, test for its underlying assumptions and make relevant interpretations.
• Explain the methods of cluster analysis and factor analysis.

• Distinguish between associations and causal effects in statistical analysis and assess their implications for policy.
• Apply statistical software to analyse and answer defined research questions and hypotheses.
• Formulate, analyse data, and write a structured applied research project.
• Confidently apply the methods of linear regression, cluster analysis and factor analysis.

• Lectures
• Guest speaker's talks (in class or in distance)
• Practical Exercises
• Collaborative Works / Assignments

Guest speaker:

• Introduction to Artificial Intelligence

Exercises:

• There are a set of meetings where we demonstrate and explain how to use the statistical software STATA, and where students are given tasks of answering and solving tasks related to the STATA and the use of large and complex data sets.
• Standard exercises concerning applied statistical calculations.

Group assignments:

• The assignments are applied research projects which you need to do with your designated group.  

Attendance is compulsory. You are strongly adviced to attend all classes. In order to count as an attending student, you must have attended at least 75% of classes. 

Students will be working in groups throughout the course. The groups will have up to 5 members and will be assigned by the professors, based on individual objective characteristics of students in order to have balanced groups.

There will be three four-hour slots during the semester where the groups meet in presence and implement a task. These group projects will count 5 points each and count towards the final grade awarded in the course. In total, students can obtain max 15 points. During the four-hour group work, students will have any tools available – including AI.

At the end of the 4-hour slots, each group must upload a written project that analyzes data using Stata and answers to the task given. 

Grading: students will be given the same grade – i.e. individual grades will be that of the group grade.

Written exam

BBoard Test, with Respondus Lockdown Browser in class. The test consists of a number of questions of the following types:

1.       Multiple Choice. Here you choose one (and only one) of the answers provided and only one of the provided options is correct (full score).

2.       Multiple Answers. Here you can choose more than one of the answer options provided. Full score is achieved if all the correct options are selected. Note that choosing a wrong option will contribute negatively to your score. The sum of the negative scores for all the wrong options is always equal to the maximum score for the question. In other words, if you select all correct and incorrect options, the score will be zero. However, in no case will the score for the question be negative (e.g. even if you choose all the wrong options and no correct option, the score for the question will be zero).

3.       Numerical Answers. Here you are required to provide an answer in numerical format, according to the required precision which is specified for each question. Please use the character “.” as decimal separator. With this format you may be required to perform calculations in order to derive your answer.

The written exam will have 16 questions and give a maximum of 16 points. This will be added to the points gained from the three group works described above.

The questions will cover theory, methods and interpretation of the results of applied research. The exam will cover all topics of the course. You will be required to analyze with Stata the data provided during the exam.

• In this course we are using the software STATA. We introduce STATA through the lectures and tutorial office hours, but bear in mind that STATA is quite user-friendly and we expect you to learn STATA through “learning-by-doing”. There are several books available for doing statistics with STATA (most of them available on Amazon). There is also a lot of online material on STATA.
