The document discusses various types of research including applied research, basic research, correlational research, descriptive research, ethnographic research, experimental research, and exploratory research. Applied research seeks practical solutions to problems, while basic research expands knowledge without a direct application. Correlational research examines relationships between variables without determining cause and effect. Descriptive research provides accurate portrayals of characteristics, and ethnographic research involves in-depth study of cultures. Experimental research establishes cause-and-effect through controlled manipulation of variables.
