Research is a systematic investigation or inquiry conducted to discover new knowledge, validate existing knowledge, or address specific questions or problems. It involves the collection, analysis, and interpretation of data to gain insights and draw conclusions. There are various types of research, each with its own objectives, methodologies, and applications. Here are some common types of research: Experimental Research: Experimental research involves manipulating variables in a controlled environment to determine cause-and-effect relationships. It typically includes a control group and one or more experimental groups and often uses random assignment. Observational Research: Observational research involves observing and documenting behaviors, events, or phenomena without intervening or manipulating variables. It can be conducted in natural or controlled settings and may involve direct or indirect observation. Survey Research: Survey research involves collecting data from a sample of individuals using questionnaires or interviews. It aims to gather information about attitudes, opinions, behaviors, or characteristics of a target population. Qualitative Research: Qualitative research focuses on understanding the meaning, experiences, and perspectives of individuals or groups. It involves collecting and analyzing non-numerical data, such as interviews, observations, or textual analysis, to uncover themes and patterns.
