Scientific Method

The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

Is one of the most effective ways to evaluate data is to try to replicate it?

One of the most effective ways to evaluate data is to try to replicate it. This also gives you the option of saving your data on different locations.

Basing managerial methods on the best available scientific evidence is called what?

Basing managerial methods on the best available scientific evidence is called evidence-based management. It is rooted in empiricism and is practiced in evidence-based policy and medicine.

Why hypotheses are incorrectly referred to as guesses?

A hypotheses is simply and educated guess. You use the information you know to be true, to make an educated guess on what will happen. Then you continue with your experiment and see if your hypotheses was correct. The largest difference between a hypotheses and a guess is simply the amount of information you apply to the question before guessing the answer.

If you state simply, "If I mashed this object and this object together, I guess Object A will break, and Object B will be just fine" That's a guess.

Now, if you actually collect the information from the two objects and note that Object A is made of high carbon steel, and Object B is made of cast iron. The mashing will happen at aprox 100mph. "I Hypotheses that given the new information about the objects, and the test, Object B will crack, or split, while Object A will remain largely undamaged"

Notice how much information is involved with one vs the other?

What are some advantages and disadvantage of adopting SI in the US?

The US will save millions of dollars wasted on unit conversion in industry

and commerce and i dont know any disadvantages

====================================

One disadvantage:

Political suicide for anybody who pushes it through. Americans still think it's an

unnecessary burden, and are firmly convinced that we should not have to put out

all that effort. If the rest of the world wants to trade with us, why then let them

change back to units we can understand. If it's still good enough for Liberia and

Myanmar, it ought to still be good enough for us. The whole thing is nothing but

another liberal plot to get power over ordinary folks. If the good lord had intended

for us to use meters, he would not have given us feet.

Do darker colors absorb more microwaves?

"Color" is a way of describing how an object interacts with electromagnetic radiation in the visible region of the spectrum.

This has no impact whatsoever on how it interacts with electromagnetic radiation in the microwave region of the spectrum. So, no, they don't.

Does the chemical reaction of carbon dioxide with other substances is called oxidation?

No. Presumably, if that were a subject of wide interest, it might be called carbon-dioxidation.

Just plain old "oxidation" is the reaction of various substances with oxygen.

Why would you try to collect 5 or more results in an experiment?

I'm assuming that your experiment was one where systematic and random errors could've occurred, yes? Simply, it is to reduce the possibility of any inaccuracies, because from collecting 5 measurements you are able to obtain an average and also judge each measurement individually to see the differences. It really will just prove whether the conducting of the experiment was consistent in correlation to the results attained.

Which freezes faster coke kool aid salted water or weak salted water?

Salted water freezes faster than weak salted water, as adding salt lowers the freezing point of the water. The presence of solute particles in the salted water disrupts the formation of ice crystals, allowing the liquid to cool more quickly and freeze at a lower temperature. This phenomenon is known as freezing-point depression.

Coke and Kool-Aid are both solutions that contain sugar and other solutes, which also lower the freezing point of the liquid. However, the concentration of sugar in these solutions is typically not as high as the concentration of salt in salted water so they may freeze at a similar rate to weak salted water.

When stating a problem that you wish to examine by means of the scientific method the problem must be what?

The scientific method is used to investigate problems relating to the natural world. You would not, for example, use the scientific method if you problem was how to assess the artistic merit of the movie "The Cabin In The Woods". But if you did have a cabin in the woods and you wanted to find out what kind of rocks were in those woods, geological science could help you.

What is a testable form of a theory?

Answer 1

A testable theory is one that can be set up to use the scientific method. In science we test for validity through verification as well as falsification, because it is impossible to conclusively verify something that can't also be falsified.

You form a hypothesis; you form a series of tests in the physical world to show if this hypothesis is true. You form many more tests to see if it is likely to be false.

If the test falsifies the hypothesis, you either revise it, or reject it in its entirety. If there is use of faith or personal belief then it is not science.

You publish your papers with the failure* or the success* of this testing or if it is just a research paper to see what is actually found, which may or may not have anything to do with the original hypothesis.

There is a formal outlined structure for using the scientific method and it must always include only physical evidence, detail the assumptions made, explain the methods used to obtain the observational data, the methods used to infer the conclusions from the data, and the methods used to both verify and attempt to falsify the conclusion.

When "science" uses opinions on evidence and ideology of what they think they see but is unverifiable that is not science. It is pseudo science.

To form a theory you must have independently verifiable physical evidence that consists of repeatable observations and never fails to show the same thing. Opinions on what people think they see is not science. That is where myths come from.

It is important to publish falsifications of standing hypotheses as well so the failed hypothesis is not perpetuated. The road to success is filled with failures. Knowing something doesn't work is important. It is only when the same results are observed again and again that you have reliable data. A good hypothesis must yield absolutely clear repeatable results when applied to the same dataset, and the same results can be achieved by any other scientist anywhere in the world using the methods detailed in the paper.

Answer 2

An explanatory claim or model is testable if it is both falsifiable as well as verifiable against observation. This requires that it be formulated in such a way as to yield specific expectations regarding observations in the here and now.

As an example, take common ancestry. Common ancestry would logically result in a pattern of nested hierarchies in palaeontology, zoology and comparative genomics. Any explanation for the variety and divergence of modern forms that did not include common descent would logically not be expected to result in nested hierarchies. If common descent were true, one should therefore logically expect to find such patterns, while assuming its falsehood would lead one to expect the absence of such patterns, making the presence or absence of such patterns a strong test for the hypothesis of common descent.

When might a scientist use a model?

When the scientist is trying to represent an object or a system.
