Question

Explanation:

To compare the spread of two data sets, we analyze the options:

• Median: Represents the middle value, not spread.
• Mode: Represents the most frequent value, not spread.
• Mean: Represents the average value, not spread.
• Standard Deviation: Measures the amount of variation (spread) in a data set. So it's used to compare the spread of two data sets.
