A fisherman was trying to figure out the best bait that he could use in order to catch more fish. He knew there was a correlation between the fish bait and the amount of fish that he could catch on a fishing trip. What is the Test (independent) variable in this experiment?

Sofie conducted an experiment where she had 3 plants to which she gave each of them different sunlight. One was in the direct sunlight, one was in the shade and the other was under large trees that only during some time during the day it received light. She measured the growth of the plant over a month and noticed they all grew at different rates. What can we conclude from this experiment?

• The growth of the plant does not correlate with the amount of sunlight.

• The amount of sunlight the plants received affected its growth.

• Sofie did not conduct this experiment correctly

• The plant with the most sunlight grew the most.

Juanita wanted to determine the effect the amount of times a betta fish was fed would affect its weight. She had 3 betta fishes all in separate tanks.

• The Betta fish

• The fish food

• The times the fish were fed

• The weight of the fish
