Syfte

The aim of the course is to aid the participants in getting a holistic view on theory of science and research process, as well as to provide advanced knowledge of quantitative methods for data analysis and an introduction of qualitative analysis. The course has an applied character with clear focus on problems common for the domain of transportation research that can be approached with a quantitative method. Besides the theoretical knowledge, the course participants will acquire practical experience in handling common software tools (Access, Excel, R, SAS, SPSS, SQL) and data formats and will learn to make data screening and data quality checks, and to calibrate regression models.

Mål

Kunskap och förståelse

För godkänd kurs skall doktoranden

• Understand the fundamental concepts of theory of science and research process;
• Have theoretical knowledge of qualitative and quantitative methods for data analysis used in transportation research;
• Understand, based on the target of the investigation, which are the appropriate tools and methods, including the limits of their applicability;
• Have a clear picture of the applicability of data analysis and regression modelling in transport research and its multidisciplinary character;
• Interpret how the quality of data and method can affect reliability of the analysis.

• Form an independent, qualified and modulated opinion on own research question (based on objective data);
• Be able to handle and learn further the most common software tools for data handling and analysis and data formats.
• Formulate a research question in a form that can be practically answered and which data and tools are necessary to answer it;

Värderingsförmåga och förhållningssätt

För godkänd kurs skall doktoranden

• Be able to critically analyse data in order to create added value and produce new knowledge;
• Be able to motivate the choice of method(s) most suitable for the given research question as well as discuss its drawbacks and limitations;
• Demonstrate an in-depth insight and ability to discuss how the quality of data and parameters of the analysis method can affects reliability of scientific research and quality of the outcome;

Kursens undervisningsformer

Undervisningsformer: Föreläsningar, seminarier, övningar, projekt. In the beginning of each theme, the participants receive instructions and reading materials, as well as practical exercises in which the new knowledge is applied. This is followed by an interactive session with the tutor in which the theoretical and exercise material are discussed. Some themes include also practical training in use of software tools. In the final assignment, the participants will apply the knowledge obtained in the course on their own research topics and datasets. They will formulate a research question, choose and motivate the method and tool to address it, perform the analysis and discuss its quality, reliability and limitations.
