What is the primary benefit of quantitative analysis when assessing whether revenue has been increasing over the past decade?

• A. Identify cause of variation
• B. Determine the average revenue
• C. Forecast future growth rate
• D. Assess profit margins

Answer: (B)

The main idea being tested is how a single numeric figure can summarize many years of revenue data. When you look at revenue over a decade, the average revenue gives you one representative value that reflects the overall level of revenue across those years. This central tendency acts as a clear baseline, letting you see whether the general level was high or low and how it compares to targets or future periods. In this context, the average is the most direct quantitative summary of the decade’s revenue.

Other options focus on different tasks: identifying causes of variation digs into why revenue moved up or down, forecasting future growth looks ahead rather than summarizing past data, and assessing profit margins shifts attention from revenue level to profitability.
