Volume Correction Formula uses which form?

• A. (Difference / Sum) x 100
• B. (Difference x Average) / 100
• C. (Average / Difference) x 100
• D. (Difference / Average) x 100

Answer: (D)

When you want to express how far apart two volume measurements are in a way that doesn’t favor either one, you use the percent difference relative to their average. That means take the absolute difference between the two volumes, divide by their average, and multiply by 100. This gives a symmetric, standard percent difference.

For example, if the volumes are 100 and 110 units, the difference is 10 and the average is 105, so the percent difference is (10/105) × 100 ≈ 9.5%.

The other forms aren’t the typical percent-difference calculation: using the sum in the denominator changes the scale based on the total, multiplying the difference by the average isn’t a percentage measure, and swapping the numerator and denominator yields a value that doesn’t reflect the actual discrepancy as a percent.
