For loss data analysis, which data organization approach is most appropriate when examining trends across multiple years?

• A. Organizing losses by date
• B. Organizing losses by size
• C. Organizing losses by location
• D. Organizing losses by cause

Answer: (B)

When analyzing trends in losses over several years, focus on how the monetary impact changes by loss size. Organizing by size reveals shifts in severity over time—whether the average loss is increasing, or the distribution is moving toward larger claims—so you can see year-to-year trend in the cost burden. This approach also lets you compare inflation-adjusted or exposure-adjusted measures like average size per claim or the share of losses in each size category, making real trends clearer. Organizing by date would highlight how many losses occur each year (frequency) but not how the losses’ monetary impact is changing. Organizing by location or by cause points to geographic or causal trends, but not directly toward year-to-year changes in loss severity.
