To determine which data set is most spread out, we need to compare their standard deviations. The standard deviation is a measure of the dispersion or spread of a set of values. The larger the standard deviation, the more spread out the data set is.
Given the standard deviations:
- Data set A: 6.06
- Data set B: 4.88
- Data set C: 5.21
- Data set D: 3.39
Let's compare these values:
1. Data set A: 6.06
2. Data set B: 4.88
3. Data set C: 5.21
4. Data set D: 3.39
From these values, we can see:
- The standard deviation of Data set A (6.06) is greater than Data set B (4.88), Data set C (5.21), and Data set D (3.39).
Thus, the data set with the highest standard deviation is:
Data set A: 6.06
This indicates that Data set A is the most spread out among the four data sets.
Therefore, the correct answer is:
B. Data set A
