Final answer:
A pilot study is primarily used for Experimental Studies, to test and refine methodologies and improve the overall quality of a larger main study. The correct option is B.
Step-by-step explanation:
A pilot study can be used for B) Experimental Studies. It serves as a preliminary small-scale version of the main study, which is designed to test and refine the methodology before implementation on a larger scale. This approach helps identify potential problems and adjust the study design to improve its feasibility, data quality, and the effectiveness of the research process.
A pilot study is not to be confused with inferential statistics, which are employed to interpret data and test hypotheses in a larger context. While pilot studies may inform the development of hypotheses, they are not solely for generating statistics from an entire population, nor are they models or representations like those used in human biology research. They are practical, hands-on preliminary investigations that inform the main study.
