A research that is conducted on a smaller amount of population is obviously easier than a
study that focuses on selecting data from very numerous groups. The population thus
represents an entire set of cases that can provide a sample, the meaning being that any person
or company that is a part of the population is of relevance for the study (Saunders et
al., 2009). In the case of this research, the full population is represented by all the companies
that carry put land transportation. The sample is represented by four companies in the
south of Sweden. The reason why these companies are from the south of Sweden is that
this region is of very high importance for transportation, it ties Scandinavia with the rest of
Europe and it is also the place where many companies have their main warehouses.
