The goal of the final exercise was to choose the appropriate technique for a small data analysis example of the participants' choice.
The data provided to the particiapnts was the indicators of well-being in OECD countries.
The data analysis could be extended by looking into additional aspects, such as the development of socio-economic factors over time or the correlation with other factors. But the participants did not need to restrict themselves to the provided data. If there is other data they preferred analyzing, they were free to do so.
The analysis could be provided in the format of the participants' choice (e.g., as interactive web site or notebook).
