Research models are structured frameworks that guide researchers in designing and conducting studies. They help in organizing thoughts, formulating hypotheses, and determining the methods for data collection and analysis. Common types of research models include qualitative, quantitative, and mixed methods, each serving different purposes based on the research question. These models also assist in interpreting results and drawing conclusions. By providing a systematic approach, research models enhance the reliability and validity of findings. They are essential in various fields, including social sciences, healthcare, and education, ensuring that research is conducted in a coherent and effective manner.
