This question asks for a comparison of two data sets using the median and interquartile range (IQR). **Average:** The median is used to compare the average age. - Swimming club median = 21.2 years. - Cycling club median = 29.7 years. Since 29.7 > 21.2, the members of the cycling club are, on average, older than the members of the swimming club. **Consistency:** The interquartile range (IQR) is used to compare the consistency or spread of ages. A smaller IQR indicates that the ages are more closely clustered together, meaning they are more consistent. - Swimming club IQR = 7.3 years. - Cycling club IQR = 4.6 years. Since 4.6 < 7.3, the cycling club has a smaller IQR. This means the ages of the members in the cycling club are more consistent (less spread out) than the ages in the swimming club.
