Accuracy refers to the degree of closeness between a measurement or prediction and the true or accepted value. It is a crucial metric in evaluating the performance of models, systems, or instruments, often influencing decision-making processes across various fields.

accuracy

Completeness in various contexts refers to the extent to which a system, theory, or dataset encompasses all necessary components or information to be considered whole and functional. It is a crucial criterion in fields like mathematics, logic, and data science, where it ensures that no essential elements are missing, thereby enabling accurate analysis, decision-making, and problem-solving.

completeness

Reliability refers to the consistency and dependability of a system, process, or measurement over time. It is crucial for ensuring trust and accuracy in various fields, such as engineering, psychology, and statistics, where repeated results are essential for validation and decision-making.

reliability

Intended use refers to the specific purpose or function that a product, system, or service is designed to fulfill, which guides its development, marketing, and regulatory compliance. It is crucial for ensuring that the product meets safety and performance standards and aligns with user expectations and legal requirements.
