Field investigations refer to research activities conducted in natural environments outside of a controlled laboratory setting. This type of research involves gathering data and evidence through direct observation, measurement, and experimentation in the field, such as forests, rivers, oceans, or urban areas. Field investigations are essential for understanding complex phenomena, collecting real-world data, and testing hypotheses in contextually relevant settings. Researchers may use tools such as sensors, surveys, and sampling techniques to gather data, analyze findings, and draw conclusions that contribute to scientific knowledge and inform decision-making processes.
