Document Summary
Researchers create situations and examine their effects on participants. They conduct experiments in laboratories/in real life with a relative small number of people and a well-focus research question. Experiments are the most effective for explanatory research. Researchers divided the people that are being studied into two or more groups, and then give only one group with the. At the end, researchers can compare the results of different groups and conclude the reaction of the treatment group . Researchers simply ask many people numerous questions, usually use a written questionnaire or during interviews and then recording answers in a short period of time. Then, answers are being summarized in percentages, tables, or graphs. Survey techniques are usually used in descriptive or explanatory research. Researchers first identify a body of material to analyze (e. g. , books, newspaper, films) and then creates a system for recording specific aspects of it. The system might include counting how often certain words/themes occur.
