Pilot studies are small-scale trial of an actual investigation. Pilot studies take place before the real study. They use fewer participants than the actual study would.
Pilot studies are used to check that the procedures of a study are good and that the investigation runs smoothly.They can be used for experimental research, questionnaires, interviews and observational studies.
Pilot studies allow researchers to identify any potential issues within the research and modify them. This helps saves money and time in the long run.
