What does the Law of Large Numbers imply in insurance?

The Law of Large Numbers is a fundamental principle in the field of insurance and statistics. It states that as the size of a sample increases, the statistical averages will become closer to the expected value. In the context of insurance, this principle underlines the importance of large data sets in determining accurate risk assessments and setting premiums.

When insurers gather a large pool of insured individuals, they are better able to predict losses based on historical data. With more examples, the random variations that might skew results in a smaller sample size diminish, leading to more dependable and stable predictions regarding claims. This reliability is crucial for the financial stability of insurance companies, as it allows them to set premiums that are both competitive and sufficient to cover projected claims.

In contrast, with smaller sample sizes, statistical calculations can be much less dependable, as they may reflect anomalies or outliers that don’t represent overall trends. Therefore, having a larger number of instances provides a more comprehensive view of the risks involved, which ultimately helps in effective premium calculation and risk management.
