Question 25

Mortality figures are usually developed by the analysis of statistics relating to the deaths of millions of individuals over extended periods of time.

Mortality figures are derived from comprehensive data that encompasses the deaths of large populations over significant time frames, allowing for accurate statistical analysis and trends.

A) Obtained by examining policyowners' records.

This option is incorrect because while examining policyowners' records may provide some insights into mortality for specific groups, it does not encompass the broader statistical analysis needed to establish general mortality figures applicable to the entire population.

B) Relating to the deaths of millions of individuals over extended periods of time.

This option is correct as it highlights that mortality statistics are primarily based on large datasets that track death occurrences over long durations, which is essential for understanding trends and patterns in mortality rates.

C) From decennial small group samples of surviving individuals.

This option is incorrect because using small group samples, especially from only surviving individuals, does not adequately reflect the overall mortality trends. Mortality figures require extensive data from both deceased and living populations over longer periods.

D) Resulting from sophisticated sampling techniques.

While sophisticated sampling techniques may be used in some studies, this option is too vague and does not specifically indicate that mortality figures rely on extensive data relating to the deaths of large populations over time, as is the case with option B.

Conclusion

The correct answer, option B, accurately captures the essence of how mortality figures are developed, emphasizing the importance of analyzing extensive data over long periods. Other options either focus on insufficient data sources or fail to address the comprehensive nature of mortality statistics, making them less valid in this context.
