Final answer:
Uncertainty Avoidance is the cultural dimension that indicates how much a society tries to avoid ambiguous or risky situations by implementing strict rules and security measures.
Step-by-step explanation:
The cultural dimension that describes a country's extent to which they feel threatened by ambiguous or risky situations is Uncertainty Avoidance. Countries with high uncertainty avoidance tend to have systems in place to minimize or avoid uncertain and ambiguous situations, valuing security and clear rules and guidelines. On the other hand, countries with low uncertainty avoidance are more comfortable with ambiguity and take a more relaxed approach to uncertainty and risk. This dimension is significant when examining cultural differences, as it can influence how societies plan, make decisions, and approach change and innovation.
