Question

question 22 of 25
these dot plots show the ages (in years) for a sample of sea turtles and a sample of koi fish.
sea turtles
dot plot for sea turtles with ages from 0 to 100, peaks around 50-55
koi
dot plot for koi with ages from 0 to 100, peaks around 25-30
what are the differences between the centers and spreads of these distributions?
select two choices: one for the centers and one for the spreads.
a. spreads: the ages of the sea turtles are more spread out.
b. spreads: the ages of the koi are more spread out.
c. centers: the sea turtles have a lower median age than the koi.
d. centers: the sea turtles have a greater median age than the koi.

Explanation:

Step1: Analyze Centers (Median)

For dot plots, the median is the middle value. Sea turtles' dots are centered around 50 - 60, koi's around 30 - 40. So sea turtles have a greater median. So D is correct, C is wrong.

Step2: Analyze Spreads (Range/Variability)

Koi's dots spread from ~20 to 60, sea turtles from ~40 to 60. Koi's ages are more spread out (wider range). So B is correct, A is wrong.

Answer:

B. Spreads: The ages of the koi are more spread out.
D. Centers: The sea turtles have a greater median age than the koi.
