AThe sample median
BCorrelation coefficient
CStandard deviation
DInterquartile range
Answer & Solution
Correct answer: B. Correlation coefficient
1. The line says what the relationship is; a second number says how strong it is.
2. The task is to calculate and interpret the correlation coefficient.
3. It measures how closely the points cluster around the fitted line.
4. Standard deviation and interquartile range describe a single variable rather than a relationship.
