Question

Leo is testing different types of greenhouse material to determine which type is most effective for growing strawberry bushes. He purchases two different brands of tarps from a local store. Leo applies brand A to an area of the yard that receives full sunlight and brand B to another area of the yard that is in partial shade. He waters both areas daily. At the end of the study, Leo concludes brand A is more effective in growing strawberry bushes. Is Leo's conclusion valid? Explain why or why not.

Answer 1

Answer:

No

Step-by-step explanation:

It wasn't an equal test. If Leo puts both the tarps in direct sunlight, then the conclusions would be fair. Brand A might have won because they got an advantage. Hope this helps.

Answer 2

Answer:

Hey there!

This is not a valid experiment because the sunshine each section received were not equal.

Let me know if this helps :)
