What are variables and how do we measure them?

Required prior knowledge: 

Students who complete this module should have a prior basic knowledge about the particularities of the quantitative research design, including understanding how a research question or a research hypothesis should be formulated, how participants for research are selected, and which method/s for data collection are most appropriate. Prior knowledge about certain procedures of data analysis is required (for example, the capacity to read and understand the results of correlation and t-test, the Cronbach’s alpha coefficient, etc.).

Module difficulty: 

Intermediate level (to understand and establish the measurement levels of variables derived from the research questions/hypothesis)

Main goals: 

• To understand how the concept of variables (independent and dependent variables) relates with the research question and/ or hypothesis
• To understand the meaning of measurement, conceptualization, and operationalization, and their interconnectedness
• To learn about the four levels of measurement (nominal, ordinal, interval and ratio).

Structure of the module: 

What does “measurement” mean?; Levels of measurement (Nominal measures, Ordinal measures, Interval measures, Ratio measures); Implications of levels of measurement in a research project; Exercises
