How does hypothesis affect a scientific investigation?

Answer 1

The hypothesis is an educated guess, it should not affect the investigation at all, it is merely a summized thought based on known evidence and a prediction of a possible outcome. A scientist however does not use that Hypothesis to get a result, they merely see if the result lines up with the Hypothesis. A quick example is you see a movie billboard, it has squirrels on it fighting, you can hypothesize the movie is about squirrels fighting. Now if you go see the movie and it has no squirrels at all, your hypothesis is wrong.... You can not go to the movie, see no squirrels, then squint your eyes really tight till the animals that are in the movie look like squirrels fighting, just to say your hypothesis was right. It should have no impact on the results of scientific study... it is merely an educated guess at a possible outcome of the tests.

Answer 2

I think it is a scientific investigation that tries to prove or disapprove a hypothesis.
