Which option shows a time period error in comparing growth data?
Answer and explanation
Correct answer: Directly comparing the ten-year growth of one area with the five-year growth of another area
Directly comparing growth over ten years with growth over five years is incorrect because the time periods are unequal. Growth over a longer period may appear larger even when its annual growth rate is lower. Option B uses the same time period and is therefore comparable, while C and D support correct interpretation of data. Exam tip: always check whether the periods are equal before comparing growth figures.
