To determine which data set is the most spread out, we need to compare the standard deviations of each data set. The standard deviation is a measure of the amount of variation or dispersion in a set of values. The larger the standard deviation, the more spread out the data is.
Here are the standard deviations for the data sets:
- Data set A: 5.21
- Data set B: 4.88
- Data set C: 3.39
- Data set D: 6.06
We need to find the data set with the maximum standard deviation. Comparing these values, we can see:
- 5.21 < 6.06
- 4.88 < 6.06
- 3.39 < 6.06
From these comparisons, it is clear that 6.06, which is the standard deviation of Data set D, is the largest. Therefore, Data set D is the most spread out.
The correct answer is:
D. Data set D
