Chances space you"ve heard of the clinical method. Yet what precisely is the scientific method?

Is the a an accurate and exact way that every science need to be done? Or is it a series of actions that many scientists typically follow, however may be modified for the benefit of an individual investigation?


The clinical Method

There are an easy methods of getting knowledge that are common to all of science. In ~ the heart of scientific research is the scientific investigation, i beg your pardon is done by complying with the scientific method. A scientific investigation is a setup for asking questions and also testing possible answers. It generally complies with the steps listed in Figure below. See http://www.youtube.com/watch?v=KZaCy5Z87FA for an introduction of the scientific method.

You are watching: Which question can be answered by following the scientific method?

Steps of a clinical Investigation. A clinical investigation typically has these steps. Researchers often construct their own actions they monitor in a clinical investigation. Presented here is a simplification of exactly how a scientific investigation is done.


Making Observations

A scientific investigation typically starts with observations. Girlfriend make monitorings all the time. Let’s to speak you take a go in the woods and observe a moth, favor the one in Figure below, resting on a tree trunk. You an alert that the moth has actually spots top top its wings the look favor eyes. Girlfriend think the eye spots do the moth look choose the confront of one owl.

Does this moth remind you of one owl?


Asking a Question

Observations often lead to questions. Because that example, you can ask you yourself why the moth has eye spots that make that look choose an owl’s face. What reason can there be because that this observation?


Forming a Hypothesis

The next step in a scientific examination is forming a hypothesis. A hypothesis is a possible answer come a scientific question, yet it isn’t just any kind of answer. A hypothesis need to be based on scientific knowledge, and it need to be logical. A hypothesis likewise must be falsifiable. In other words, it should be feasible to make monitorings that would disprove the hypothesis if it really is false. Assume you understand that some birds eat moths and also that owls prey on other birds. From this knowledge, you reason that eye clues scare far birds that could eat the moth. This is her hypothesis.


Testing the Hypothesis

To test a hypothesis, you very first need to make a prediction based on the hypothesis. A prediction is a statement that tells what will occur under particular conditions. It have the right to be expressed in the form: If A occurs, then B will certainly happen. Based upon your hypothesis, you might make this prediction: If a moth has eye spots on that wings, climate birds will prevent eating it.

Next, you must gather evidence to test her prediction. Evidence is any kind of data that may either agree or disagree with a prediction, therefore it may either support or disprove a hypothesis. Evidence may be gathered by one experiment. Assume that you gather proof by making an ext observations that moths v eye spots. Probably you observe the birds really perform avoid eat moths v eye spots. This evidence agrees through your prediction.


Drawing Conclusions

Evidence the agrees with your prediction supports your hypothesis. Go such proof prove the your theory is true? No; a hypothesis cannot be proven conclusively to be true. This is since you can never examine all of the feasible evidence, and also someday evidence might be discovered that disproves the hypothesis. Nonetheless, the more evidence the supports a hypothesis, the more likely the theory is to it is in true.


Communicating Results

The last action in a scientific investigation is interacting what you have actually learned through others. This is a an extremely important step due to the fact that it enables others to test her hypothesis. If various other researchers gain the same results as yours, they add support come the hypothesis. However, if castle get different results, they might disprove the hypothesis.

When scientists share your results, they should describe their methods and allude out any feasible problems with the investigation. Because that example, when you were observing moths, maybe your existence scared bird away. This introduce an error into your investigation. You got the outcomes you predicted (the bird avoided the moths when you were observing them), however not because that the factor you hypothesized. Other researchers might have the ability to think of methods to protect against this error in future studies.

The Scientific technique Made Easy describes scientific method: http://www.youtube.com/watch?v=zcavPAFiG14 (9:55).


As you check out The Scientific an approach Made Easy, emphasis on this concepts:

the relationship between evidence, conclusions and theories, the "ground rules" of clinical research, the measures in a scientific procedure, the meaning of the "replication of results," the definition of "falsifiable," the outcome once the scientific an approach is no followed.
