From the results in the experiment the best conclusion is : ( B ) they are not valid because the student did not control all the variables that can affect plant growth

Experimental varables

The growth variables such as amount of light and amount of water need for the plants to grow effectively are not controlled in the experiment. The first group was hand watered while the second group was watered with a sprinkler therfore the amount of water reaching both groups are not the same therefore the experimental conclusion is not valid.

Hence we can conclude that From the results in the experiment the best conclusion is : ( B ) they are not valid because the student did not control all the variables that can affect plant growth.
