You decide to test the effects of Miracle Grow fertilizer on plant growth. Group A is given fertilizer once a week for 4 weeks. Group B is given no fertilizer. The plant height of both groups is measured daily. Which of the following is a possible source of error? • Group A has 2 plants and Group B has 10 plants • Group A is kept in the sun and Group B is kept in the shade • Group A is given 100 ml of water each day and Group B is given 50 ml of water each day • All of the above
You decide to test the effects of Miracle Grow fertilizer on plant growth. Group A is given fertilizer once a week for 4 weeks. Group B is given no fertilizer. The plant height of both groups is measured daily. Why is it necessary to have Group B as your control group? • The control group makes your results invalid • The control group is a possible source of error • The control group is used for comparison • None of the above
