What are the benefits of a pilot study?

Advantages include: Establishes the validity of research based upon the expert knowledge of other researchers in the discipline, therefore preventing falsified work from being accepted within an area of study. Provides valuable feedback so that researchers can revise and improve their papers before publication.

How does a pilot study increase validity?

Pilot studies have an important role in intervention development and, when interpreted appropriately, can increase the efficiency and validity of subsequent clinical trials by improving subject recruitment and intervention delivery and by enabling investigators to more accurately determine sample size requirements.

How many participants do I need for a pilot study?

12 participantsWe recommend at least 12 participants for pilot studies with primary focus of estimating average values and variability for planning larger subsequent studies. This size is quite practical for most early‐stage investigators to conduct within single centers while still providing valuable preliminary information.

What is a good sample size?

A good maximum sample size is usually 10% as long as it does not exceed 1000. A good maximum sample size is usually around 10% of the population, as long as this does not exceed 1000. For example, in a population of 5000, 10% would be 500. In a population of 200,000, 10% would be 20,000.

How is pilot study conducted?
