Veracity refers to the accuracy and truthfulness of information. It is an essential quality in various fields, including journalism, research, and data analysis. Ensuring veracity helps maintain trust and credibility, as false or misleading information can lead to confusion and poor decision-making. In the context of data, veracity is one of the key dimensions of big data, often discussed alongside volume, variety, and velocity. High veracity means that the data is reliable and can be confidently used for analysis, while low veracity indicates potential errors or biases that may affect outcomes and interpretations.
