Answer:
C. The typical value is greater in set B. The spread is greater in set A.
Explanation:
A typical value is the center of the dot plot, which is often found by finding the mean or median of the set. Both sets have 5 dots plotted. The spread of a set is how far the plotted values are from this center (mean or median).
Set A is shown to have more data spread out; values range from 0 to 7.
- Center: (0 + 2 + 3 + 5 + 7)/5 = 3.4.
- Spread: 7 - 3.4 = 3.6 from the maximum to the center. 3.4 - 0 = 3.4 from the center to minimum.
Set B is shown to have data that is more condensed and at higher values; ranges from 6 to 9, with two of the five points plotted at 6.
- Center: (6 + 6 + 7 + 8 + 9)/5 = 7.2.
- Spread: 9 - 7.2 = 1.8 from the maximum to the center. 7.2 - 6 = 1.2 from the center to minimum.
Set B has a higher typical value. Set A has a greater spread.
