a controlled experiment allows the scientist to isolate and test what?

Question

is it
a. a conclusion
b. a mass of information
c. several variables
d.a single varible

Answer 1

d. if there a several variables, you don't know which one is responsible. so you can only test 1 at a time

Answer 2

A controlled experiment allows the scientist to isolate and test :
d. a single variable

I learned about independent and dependent variables last quarter and it makes the most sense in this case to go with the answer of d. a single varibale because when you are using a control, you are testing one thing against something normal. For example, if you were trying to test which energy drink gave you more engery, you would have your control as someone who didnt drink an energy drink and your independet variable would be the type of energy drink being dranken. I dont know if that makes sense to you but Im trying to make it as clear as I can. I hope this helps you out.

Answer 3

while there are quite a few attainable aspects which may be inflicting the effect a thank you to locate which one is the specific reason is to administration all yet one ingredient. protecting all yet one controlled around the test leaves an autonomous variable energetic. If it reasons the envisioned effect it, and in undemanding terms it, replaced into the reason of the outcomes. A controlled test isolates the energetic theory or the energetic variable and demonstrates a right away causative hyperlink with the based consequences.

Answer 4

d. a single variable ... which will help in making th conclusion , cuz without the control a concrete conclusion cannot be reached, a control demonstrates the absence or presence of a single variable!!!....so yes.. the answer is {d}

Answer 5

It should be d.
You keep all the variables under control, so you can establish what function is a variable with respect to the others.

Answer 6

why don't you read your book? I'm sure the answer is it.
