Final answer:
The characteristic of quality data that signifies it is free from errors is called Accuracy. It ensures that data is not only consistent but also correct and without mistakes.
Step-by-step explanation:
The characteristic of quality data that means the data is completely free from any errors is Accuracy. This concept is distinct from reliability, which refers to the consistency of a measure, ensuring that the same results are produced under the same circumstances. However, reliability does not guarantee accuracy; a measurement could be reliable, producing consistent results, but still be inaccurate if it is not correctly calibrated or if there are systemic errors in the data collection process. For instance, a scale could reliably show the same weight each time you measure an object, but if it's not calibrated correctly, the weight it shows is not accurate. Therefore, the correct answer is D. Accuracy.
