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
Fish Size 4 cm, 8 cm, 14 cm,
110 cm, 6 cm, 2 cm
Pond B 14°C
6 cm, 8 cm, 10 cm,
110 cm, 12 cm
Pond C 18°C Pond D 20°C
5 cm, 8 cm, 12 cm, 8 cm, 10 cm, 10 cm
14 cm, 10 cm, 20 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 temperature is related to the size of fish.
