Which of the following is a data quality metric?

• A. Uptime.
• B. Latency.
• C. Accuracy.
• D. Throughput.

Answer: (C)

Data quality metrics measure how trustworthy data is for decision-making. The metric that fits data quality most directly is accuracy, which checks whether the stored data values reflect the true values. For example, if a record lists a person’s birth year, accuracy means that year is correct. The other options describe system performance: uptime is how often the system is available, latency is the delay in response, and throughput is how much data the system processes in a given time. These assess speed, availability, or capacity, not whether the data itself is correct. Therefore, accuracy is the data quality metric among these choices.
