This document discusses different types of research methodologies. It begins by defining research and distinguishing between qualitative and quantitative research. Qualitative research deals with phenomena that are difficult to quantify, such as beliefs and meanings, and aims to gather an in-depth understanding of human behavior. Quantitative research refers to systematic empirical investigation using statistical techniques to develop and test hypotheses. The document then covers several specific types of research methodologies, including basic research which expands knowledge versus applied research which seeks practical solutions, experimental research which tests hypotheses, survey research which collects data through surveys, ethnographic research which studies culture through observation, historical research which studies past events, and correlational research which investigates relationships between variables.
