The answer I believe would be talking to plants may or may not helps plants grow faster because the amount of water given was likely different for each group. I say this because there are more than one manipulated variables. (Each experiment should only have one manipulated variable to really be able to come to a conclusion) The student wants to see if talking to the plant will help. But the student also used different watering methods. So there was more than one manipulated variable. This can not give a good enough result because we do not know which affected the plant- the talking or the watering method/amount.
Hope this helps!
