How to choose and compare
Summarize or compare numbers
Average provides several summary measures: a mean can move sharply with an outlier even if the median barely changes. Ratio simplifies relationships, while Fraction keeps numerator and denominator operations explicit.
Check the result convention
Confirm angle mode in Scientific, the base in percentages, and the stated grading convention in Marks Percentage. CAGR summarizes growth between endpoints; it does not describe the intervening variation. Rounded output is not exact symbolic arithmetic.
