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.

What is popper's scientific method?

Basically and simply.

All hypotheses and theories must be falsifiable in principle.

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.

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?

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.

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.

What is prior hypothesis bias?

People tend to like the first idea they hear and are hesitant to hear other ideas that clash with the first idea.

What step in the scientific method do you make inferences?

What two research methods did Laud Humphreys utilize in his classic tearoom study?

Laud Humphreys produced a 1970 ethnographic survey of homosexual encounters in public places. Public restrooms were known euphemistically as tearooms. His methods would be considered unethical today. He observed the behavior of people without their knowledge or permission. He also followed them using their license plates and asked them to fill out a questionnaire, whose purpose was different than he told them: a social health survey. Finally, he published the results without notifying the participants, which violated their privacy.
