Why is a hypothesis important to scientific investigation?

Answer 1

The hypothesis tells what you believe to be the reason behind the observation.

Example:
Observation: I see more butterflies in my front yard than in my back yard.
Hypothesis: The flowers in my front yard are more attractive to butterflies than the flowers in my back yard.
Hypothesis: The front yard is bigger than the back yard.
Hypothesis: The front yard gets more sunshine than the back yard.
Hypothesis: The front yard has a puddle of water and the back yard does not have a puddle of water.

Then you design an experiment to test the hypothesis you have chosen as being the most likely explanation.

Answer 2

In a scientific investigation, you are trying to check out some characteristic. You may have to do an experiemnet. This is to be designed to verify some aspect. You need a hypothesis to device the experiement and 'prove' or 'fail to prove' what you set out to check.

Answer 3

The hypothesis is not the same as the problem statement.
You need to state a possible solution to the problem (your hypothesis) so you can test it. The simplest solution is often the best solution.
If your hypothesis is wrong, you can form a new one. The original problem is still the same. The hypothesis, or possible solution can be varied as often as necessary.

Answer 4

It is C This is because the only difference between the control and experimental test and the control test is one variable. This means that any different results can be attributed to the changed variable.

Answer 5

You have to have a target idea to prove or disprove.
