Group 2 drinks 50mL of the soda pop while they work. Group 3 is not given the soda pop while they work. 3. Controlled variable: After an hour, Gru counts how many sets of papers each group stapled. He made the data table below. Group 1 Group 2 Group 3 2. Dependent Variable: 4. What should Gru’s conclusion be? How did the soda pop affect the number of papers each group stapled? Use data (numbers) to support your answer. Number of sets of paper stapled 2 200 1 703 980 Dr. Nefario notices that his window is covered in a strange blue glitter.
