Astudent conducted an experiment to test whether talking to plants would them to grow faster. the student talked to one group of plants and hand watered them. the student did not talk to the other group of plants and used sprinklers. after three weeks, the plants that were spoken to showed much more growth than the plants that were not. based on the results of this experiment, which is the best conclusion?
a) talking to plants may or may not plants grow faster because three weeks is not enough time to tell.
b) talking to plants may or may not plants grow faster because the amount of water given was likely different for each group.
c)talking to plants does not plants grow faster because the experiment did not involve enough groups of plants to determine this.
d) talking to plants does plants grow faster because those plants showed more growth.

The correct answer is option B, that is, talking to plants may or may not help plants grow faster because the amount of water given was likely different for each group.

Explanation:

In my opinion, there is the presence of more than one manipulated variables. It is a fact that each of the experiment must exhibit one manipulated variable in order to come to a possible conclusion. In the experiment, the student desires to see if talking to the plant will assist, however, the student also utilized various methods of watering. Thus, there is the presence of more than one manipulated variable. Thus, it is not possible to provide an accurate outcome as what influenced the growth of the plant: methods of watering or talking.
