ABSTRACT
The purpose of research is to gain new knowledge. In order to be able to trust new findings, it is important that scientific methodology is used. The tools that researchers use to conduct research should be described in sufficient detail so that other researchers may conduct and replicate the study. In other words, an important principle is that the findings should be replicable, which means that they are confirmed in new studies and by other researchers. There are several scientific methods available, and the most important aspect is that the methods are well suited for exploring the research question. Sometimes, the best choice is to use an experiment, whereas at other times a survey may be the best choice.
