A pilot experiment, pilot study, pilot test or pilot project is a small-scale preliminary study conducted to evaluate feasibility, duration, cost, adverse events, and improve upon the study design prior to performance of a full-scale research project.
There is no formal definition for these two sub-categories, but generally: Phase IIa studies are usually pilot studies designed to find an optimal dose and assess safety ('dose finding' studies). [15] Phase IIb studies determine how well the drug works in subjects at a given dose to assess efficacy ('proof of concept' studies). [15]
In drug research, a pivotal Phase III trial may be referred to as a "therapeutic confirmatory study", [1] and is conducted in a large number (hundreds to thousands) of subjects. [2] Such pivotal trials are also designed to discover and estimate the prevalence of common adverse events, but based on their size only have the statistical power to ...
Most researchers attempt to test the construct validity before the main research. To do this pilot studies may be utilized. Pilot studies are small scale preliminary studies aimed at testing the feasibility of a full-scale test. These pilot studies establish the strength of their research and allow them to make any necessary adjustments.
Exploratory research is "the preliminary research to clarify the exact nature of the problem to be solved." It is used to ensure additional research is taken into consideration during an experiment as well as determining research priorities, collecting data and honing in on certain subjects which may be difficult to take note of without exploratory research.
In January 2017, another pilot study, designed for two years, was launched by the charitable organization Eight in an undisclosed village consisting of 50 households. The experiment, which is being recorded in a documentary, aims to evaluate the effects of basic income in four areas: education participation of girls and women, access to ...

A pilot study may be run before a major experiment, in order to try out different procedures, determine optimal values of the experimental variables, or uncover weaknesses in experimental design. The pilot study may not be an experiment as usually defined; it might, for example, consist simply of self-reports .
