The reliability of data primarily refers to its consistency over time, which is why the chosen answer accurately encapsulates this concept. When data is reliable, it means that if you were to collect it repeatedly under the same conditions, you would obtain the same results. This consistency is crucial in Continuous Quality Improvement because decision-making relies heavily on stable data to identify trends, monitor performance, and implement effective improvements.
