Marlin conducted an experiment in which  independent variable is receiving an ointment and an dependent variable is number of anemone stings.

The people in the control group were neighbors in group B. The independent variable is the application of the ointment. The dependent variable is the number of  anemone stings. Marlin’s conclusion should be that the ointment was successful in reduce the stinging power of the anemone.  The eight people in group B reported feeling better because they believed that they were receiving the protective ointment.

An experiment must always have a dependent variable and an independent variable. The dependent variable is the variable that changes when the independent variable is manipulated.

In this case, the dependent variable is the number of anemone stings and the independent variable is the application of the ointment.

The experimental group (group A) received the ointment and a significant number of 30 participants reported feeling better meaning that the ointment was successful at protecting participants from anemone stings.

The control group (group B ) did not receive the ointment but received a placebo. Eight participants in that group reported feeling better because they believed that they received the protective ointment.

The experiment is successful and the ointment have been shown to protect people against anemone stings because more than 60% of the participants in the experimental group reported lesser anemone stings whereas only 16% of participants in the control group reported feeling better.
