Document Summary

Experiment is when you modify something in a situation and then compare an outcome to what existed without the modification. Three things researchers do in experiments: begin with hypothesis, modify something in a situation, compare outcomes with and without the modification. Best way to test causal relationships because the three conditions for causality (temporal order, association, and no alternative explanations) are best met in experiment designs. Match between research question and technique is not fixed but rather depends on informed judgment (develop judgment from reading research reports, understanding strengths and weaknesses of different techniques, assisting others with their research or through personal experience) Questions appropriate for using an experimental logic confront ethical and practical limitations of intervening in human affairs for research purposes. Immoral and impossible to manipulate certain areas of human life. Therefore, experiments are limited to research questions in which a researcher is able to manipulate conditions.
