Dataset P records eight manufacturing quality-review counts: 4, 6, 9, 11, 14, 18, 23, 27. Dataset Q replaces only the largest value: 4, 6, 9, 11, 14, 18, 23, 40.
Using the split-half convention (each quartile is the median of its half), which statement about their interquartile ranges is true?
- Dataset P's IQR is greater than Dataset Q's IQR.
- Dataset Q's IQR is greater than Dataset P's IQR.
- The two IQRs are equal.
- The relationship cannot be determined without knowing the exact new maximum.
- Dataset Q's range is smaller than Dataset P's range.
