Document Summary
Experimental research builds on the principles of a positivist approach. The experiments basic logic extends common sense thinking. Common sense experiments are less careful or systematic than scientifically based experiments. Experimental research is the strongest for testing causal relationships because the three conditions for causality (temporal order, association and no alternative explanations) are best met in experimental design. The match between a research question and technique is not fixed but depends on informed judgment. You can develop judgment from reading research reports, understanding the strengths and weaknesses of different techniques, assisting more experienced researchers. The experiment allows a researcher to focus sharply on causal relations and it has advantages and disadvantages. The questions appropriate for using an experimental logic confront ethical and practical limitations. It is immoral and impossible to manipulate many areas of human life for research purposes. The experiment is limited to research questions in which a researcher is able to manipulate conditions.
