Question

SOMEONE PLEASE HELP ME! THIS IS NEEDED ASAP!!

Phil wanted to know which insect spray worked the best to kill ants. He obtained three types of insecticide: Raid, Meijer and Target brands. He thought that the Raid brand would do the best job. Next he sprayed Raid for 3 seconds on a known ant path. He sprayed Meijer brand for 3 seconds on another known ant paths and third, he sprayed Target brand for 3 seconds on another known ant path. Phil checked on the ant path several times during the day and the data table contains his findings. After each check, Phil cleared the dead ants.

What is the DEPENDENT variable in Phil's experiment?

a The number of dead ants
b The ant paths
c The time intervals
d The different types of insecticide

Answer 1

The dependent variable in Phil's experiment is the number of dead ants. The dependent variable is the variable that is being measured or observed in an experiment. In this case, Phil is interested in finding out which insect spray works the best to kill ants, so he measures the effectiveness of each spray by counting the number of dead ants on each known ant path.

By spraying each brand of insecticide for 3 seconds on separate ant paths and then observing the number of dead ants on each path, Phil can compare the effectiveness of the different types of insecticide. The number of dead ants is what he is measuring and what he expects to vary depending on the type of insecticide used. Therefore, the number of dead ants is the dependent variable in Phil's experiment.

Answer 2

The dependent variable is a) the number of dead ants
