Exercises: Interpret Shape, Center, and Spread in Context
Work through each section in order. For interpretation problems, write in complete sentences about the real-world quantity, not just numbers. Remember: skew points toward the TAIL, the median and IQR resist outliers while the mean and standard deviation do not, and "lower" or "higher" is good or bad only relative to what is being measured.
