1. The plural of observability; the quality or state of being able to be observed or noticed.
Usage: Often used in technical or scientific contexts.
2. In systems engineering and control theory, the degree to which the internal states of a system can be inferred from its external outputs.
Usage: technical; systems engineering

Examples

• The observabilities of different astronomical objects vary greatly depending on their distance and brightness.
• Engineers assessed the observabilities of system states to ensure proper monitoring.
• The observabilities of quantum particles present unique challenges in physics.
• Improving observabilities in the network helped technicians diagnose problems more quickly.
• The study examined the observabilities of behavioral patterns in the research subjects.
