Which of the following is NOT an assumption that scientists make when doing experiments?

Question

a. There is no reasonable alternative to their hypothesis.
b. Another person would record the same results.
c. Only natural causes are involved.
d. The same thing would happen at other places and times.
e. All of the above are assumed.

Answer 1

a is clearly false. Scientists try to think up reasonable alternaties to their own hypotheses. It is always possible someone might come up with something they had simply not considered.

Answer 2

A

A hypothesis is an educated GUESS - if an experiment fails to answer their guess, then they form a new hypothesis and try again. Hypotheses drive the experimentation process-there are always alternatives

Answer 3

a - scientists must be open to any possible answer and must consider everything until that thing is proven wrong.

many experiments supporting a hypothesis does not make that hypothesis fact.
but one experiment DISPROVING the hypothesis loses all the credibility of that hypothesis

so, untill proven wrong, scientists must not assume that there is no resonable alternative to their hypothesis!

hope that is clear enough.

Answer 4

a. if there was not reasonable alternative to their hypothesis, what's the point of doing the experiment.

Answer 5

A. Scientists always try 2 disprove their stuff rather than prove it.

Answer 6

a. There can be many different hypotheses to explain a phenomena, and a scientist stays open to them all.

Answer 7

a. There is no reasonable alternative to their hypothesis.

Answer 8

c. Only natural causes are involved.

Answer 9

I'm no scientist, but I would definitely guess "A".
