Question
A biology student wanted to determine if using fertilizer would promote plant growth. The student randomly selected
20 plants and randomly assigned 10 of them to a large square container and the other 10 to a different large square
container. Both containers had the same amount of soil and received the same amount of water and light. One
container also received fertilizer and the other container did not.
Is this a valid experimental design?
O Yes, each plant was randomly assigned to the large containers.
O Yes, the variables not being measured-soil, water, and light-were controlled.
O No, both containers did not receive the fertilizer.
O No, the experiment did not use replication of the experimental units.
