Question

Can someone check my answer, please? :)


1. One way in which experimental research differs from observational research is that only experimental research can

*show cause and effect
*test a hypothesis <<<
*produce scientific results
*support a theory

I was caught between A & B, but I'm thinking B?

Answer 1

One way in which experimental research differs from observational research is that only experimental research can

show cause and effect

Answer 2

NathalyN is correct the correct answer is A show cause and effect

Answer 3

The key is in "show". Here it is a synonym for "demonstrate". How would you demonstrate something if you ware just observing?

Answer 4

I think it is B because we do an experimental research to test the hypothesis right?
And besides by using the observational hypothesis we can't test the hypothesis.

Answer 5

To reply to this question, I will try to apply a method.
I'll wonder for each eventual answer:

1/ if observation can
2/ if experimenting can.

*show cause and effect --> I think you can see causes and effects by observing. For instance, you show your dog a sausage (cause), and it salivates (effect), like in the Pavolov experience.

*test a hypothesis ---> To test hypothesis, you need experimenting you can't test hypothesis just by observing.

*produce scientific results ---> To produce scientific results, you need to test, to experiment.

*support a theory ---> you have to make a theory and test it, so I think you need experimenting.

I'm not sure of my answers, but I'm sure the method is good. Try it.

Answer 6

So my answers are, experimenting is necessary for:
- testing an hypothesis
- producing scientific results
- supporting a theory.

Answer 7

*Pavlov

Answer 8

Maybe it's all the answers, if the word "show" means demonstrate. English is my second language, so I've some doubt. But you have the method, try.

Answer 9

gud one @PERCE-NEIGE

Answer 10

It is a horrible question. B is the most likely answer, but even that could be done via observations.
