What is a pilot study typically used for?

A pilot study is typically employed to test methods and gather relevant information using a small sample before launching a larger-scale research project. This preliminary study allows researchers to identify potential problems in the research design, procedures, and instruments they plan to use. By using a smaller sample, researchers can gauge feasibility, time, cost, and adverse events, along with refining their hypotheses and questions based on the preliminary data.

In contrast, collecting data from a large population is the aim of a full-scale study, not a pilot study. Analyzing existing data sets pertains to secondary data analysis rather than a pilot study, which focuses on new data collection methods. Finalizing research questions typically occurs after the pilot study is conducted; hence, a pilot study allows for adjustments to be made based on initial findings. Thus, the use of a small sample in a pilot study is essential for informing and improving the main research project.
