How does an analyst ensure that a data source is reliable?

Reliable data means information you can trust, which comes from being accurate, complete, and unbiased. Accuracy means the values reflect reality and are correct; completeness means the data covers all the necessary aspects so important information isn’t missing; unbiased means the data isn’t skewed by the source’s preferences or external influences. When these qualities are present, an analyst can rely on the data to support decisions and insights. Relying on a single source can introduce unrecognized errors or biases, and speed of access or having many fields doesn’t by itself guarantee reliability—fast data can be incomplete or biased, and many fields can add noise if the data quality isn’t solid.
