3. A biologist studying ponds in Alaska wants to determine if the temperature of a pond affects the length of the fish in that pond. He traps and measures fish in
each pond, gathering the following data:
Pond A 10 °C
Pond B 14 °C
Pond C
18 °C
Pond D
20 °C
Fish Size
4 cm, 8 cm,
14 cm,
10 cm, 6 cm, 2 cm
6 cm, 8 cm, 10 cm,
10 cm, 12 cm
5 cm, 8 cm, 12 cm,
14 cm, 10 cm, 20 cm
8 cm, 10 cm,
10 cm
14 cm, 24 cm
Choose a way to represent this data using either a bar graph or a scatter plot. Then write a summary of
the data to answer the question as to whether the temperature is related to the size of the fish.
