Problem

Interpret this quiz-score display evidence and its limits: classes C and D have equal medians, but \(IQR_C\) is much larger than \(IQR_D\). State the center and spread meanings, the supported contextual conclusion, and an unsupported claim.

Source distribution display: Display evidence: Classes C and D have equal medians, but IQR_C is much larger than IQR_D. No requested comparison or interpretation is annotated.

center evidence=equal medians→same typical quiz score; spread evidence=larger IQRC→D less consistent; supported=same typical score with D more variable; unsupported=IQR direction matters

center evidence=equal medians→same typical quiz score; spread evidence=larger IQRC→less consistent/more variable middle50% for C; supported=same typical score with lower consistency for C; unsupported=C typically scores higher

center evidence=equal medians→C typically higher; spread evidence=larger IQRC→more variable middle50% for C; supported=C typically scores higher and is less consistent; unsupported=equal medians determine a higher center

center evidence=equal medians→same scores overall; spread evidence=larger IQRC→same variation; supported=identical score distributions; unsupported=IQRs may differ without changing the conclusion
