What is the next step in an experiment if the results are statistically significant?

Assuming you have done all of the necessary analysis and graph plotting, the next stage would be to write up your results in a report and derive an equation to describe the trend.
Then repeating the experiment to ascertain whether the results are repeatable would be a good idea!

What does scentific method mean?
Scientific MethodThe scentific method sets for a process for investigating the world around us. It is a multistep process that begins with identifying a question. This is followed with the development of a hypothesis, in other words, an educated guess as to what you think will happen or how you think the question will be answered. The next step is to construct an experiment. To do that you need to make a list of the steps and procedures for the experiment and then you must gather the equipment to carry out the experiment. Performing the experiment is obvious, but just as important is recording the results of the experiment and drawing a conclusion about what the experiment said about your original question and your hopothesis.
Why is statistical significance important?
Because there are so many things that happen - some predictably, some coincidentally - that all fall into the category of random "chance" - it's this way one time, that way the next. Statistics are carefully calculated to have a cut-off point, below which is considered to be within the category of "random". Above that figure, it is more frequent than "random" can explain. At that point, it becomes - to a greater or lesser degree - "statistically significant". A simplistic example: If a child has a school year 180 days long, and the child is "home sick" seven out of those 180 days, that is within the realm of random. If the child is "home sick" 57 of those 180 days, that is "statistically significant".
What 2793149 rounded to the nearest hundred thousand?
2,793,149 rounded to the nearest hundred thousand would be 2,800,000. The "hundred-thousands" place is 7, and the next most significant digit is 9. If the next-most-significant digit is 4 or lower, we round down; if it's 5 or greater, we round up. Since the "next-most-significant digit" is 9, we round up from 7 to 8.
What is 0.209 rounded to 1 significant figure?
The first step in taking any number to 1 significant figure is to find the greatest non-zero digit. In this case it is the 2, as that represents 2 tenths. The next step is to look at the next digit on. If it is 5, 6, 7, 8 or 9 we need to round up. Otherwise, we can leave it as it is. The next digit is 0, so we don't need to round up. Therefore 0.209 rounded to 1 significant figure is 0.2
What does the 6 in 32.60 round to?
If you are rounding off to two significant figures the result is 33.Sixes always round up to the next higher digit i.e.296 to two significant figures is 30 *101
What was Mendel's results to his first experiment?
He found out that some traits in one generation (parents) was not present in the next generation (offspring).
An experiment testing the hypothesis that nitrogen markets shoot farther that carbon dioxide markets resulted in conflicting test results the researchers rejected their hypothesis What they do next?
think of alternative explanations for their results
What do you do to test a hypothosis?
First you ask a question about what you want to learn, Then you do some research, Next you construct a hypothesis, Then you test the hypothesis by doing an experiment, Next you Analyze your data and draw a conclusion, Communicate your results. And that is the hypothesis.
Could an experiment that fails to achieve predicted results ever be considered a success?
Absolutely Analyzing the data from your failed experiment, allows to form some new theories and draw conclusions to move forward into your next bit of research. This failure, so to speak, can be used as the impetus for your next adventure in discovery. The answer is just around the corner.
What should you do next when the experiment get an unexpected result?
you must repeat and redo the experiment
Conclusion in science projects?
The conclusion in your scientific reports should include: * what were the assumptions and what results were you expecting before doing the experiment * what method(s) or approach(es) did you use in the experiment * what are the results? * do your results agree or support with your assumptions? If yes, why? If no, what do you suggest to do for the next experiment. Preferably, the conclusion is much shorter than the body of your report. One paragraph can suffice, but try to keep it less than 2 typewritten pages. Be concise. Keep your sentences short. This section may be the only one that your peers or superiors will read. ==================
What does rerun stand for?
R:recall-describe what you did (briefly) E:explain-tell the purpose of the study R:results-state the results including the hypothesis that was supported U:uncertainties-what might have affected your experiment N:new/next time-what new things did you learn/what would you do differently next time
How do scientist conduct a scientific investigation?
They draft a hypothesis, investigate it. Next, they conduct several experiment's, if they can get good repeatable results others test it. Then it is improved or accepted and over time it may change or disappear completely.
Is jasmine weird?
VERY!!! im sat next to her. Statistically she should be in a mental hospital along with her friend.. not naming any names... ;)
How long should the conclusion of an experiment be?
it doesnt have tobe very long, only about as big as the hypothesis - - - - - - - - - - about 2 paragraphs - make sure you include everything you need to - the results, why you think the results came out like they did, do they match your prediction (if you did one), how you could improve next time, and anything else you've been asked to include

What are the limitations if you conducted experiment one time?
one limitation is a very small data set (it's hard to tell if the result is going to be different next time). Which brings up the subject of variability - are the initial conditions always the same (will my beaker be a little dirty or contaminated next time, will my lab partner click the stopwatch at exactly the same time, will I be distracted at the end of the experiment and miss an important detail...). A good experiment is repeatable, a bad one gets different results each time.
