What is the function of a "Data Dictionary" in survey analysis?

The function of a "Data Dictionary" in survey analysis is to offer definitions of variables and fields. This essential component serves as a reference guide that outlines the meaning, format, and purpose of each variable collected during the survey process. By clearly defining what each variable represents, researchers and analysts can better understand the data at hand, ensuring accurate interpretation and effective analysis. This aids in data integrity and consistency, making it easier to communicate findings and collaborate with others who may be working with the same dataset. The presence of a comprehensive data dictionary also minimizes the risk of misinterpretation and confusion regarding the variables and how they should be used in analysis.
