A research study is a systematic investigation aimed at answering specific questions or testing hypotheses. Researchers collect data through various methods, such as surveys, experiments, or observations, to analyze and draw conclusions. The findings contribute to the existing body of knowledge in fields like psychology, medicine, or education. In a typical research study, participants are often selected based on certain criteria to ensure the results are relevant. The study may involve a control group and an experimental group to compare outcomes. Ultimately, the results are published in academic journals, allowing others in the field to review and build upon the work.
