Two groups tested a rolling ball. Mat 1 speeds were 7, 7.5, 8, 8, 8.5, and 9 cm/s. Mat 2 speeds were 6, 7.5, 8, 8.5, 9, and 10.5 cm/s. Which statement best compares the two sets?
A
Both mats have a similar center near 8 to 9 cm/s, but Mat 2 has a wider spread because it includes 6 and 10.5 cm/s.
B
Mat 1 is less consistent because all of its speeds are close together.
C
Mat 2 has no value above 9 cm/s.
D
The two data sets cannot be compared on a line plot.
