A scientist performs an experiment The results of the experiment disagree with a scientific theory The scientist repeats the experiment several times and gets the same results The scientist then?
The scientific theory should be changed.
Why is it important for a scientists to repeat an experiment several times?
Theories have to be proved A true scientist will repeat the same experiment several times to check the accuracy of his/her data. They will also use controls of the same type to make certain the experiment is stable. After they have concluded the experiment is true then they will publish it and allow other scientists to preform the same experiments to prove it correct. In every experiment there are many variables and different conditions that can be experienced. From this knowledge a true scientist will make sure that under all circumstances the experiment will hold true.
Why do scientists repeat experiments?
Scientists repeat experiments for reliability. The experiment must be repeated for the scientist to develop a theory. One experiment does not prove your hypothesis correct; therefore, it must be done a several times.
How many times should you repeat an experiment?
You should do it enough to see a clear pattern among the results. Or if you're doing it for like an elementary school science fair, just do it like 2 or 3 times, b/c they just want to know you thought of repeating the experiment. In middle school students are supposed to do it at least 10 times.
Should scientists repeat experiments to see if their data is reproducible?
Scientists make more mistakes than not. It is part of the business and why they call their work "experiments". As a working scientists you try to keep your basics constant. You control the pH of your solutions, the don't switch suppliers for even basic salts mid-experiment. Most importantly you repeat experiments several times and use statistical analysis to support your conclusions. The goal of scientist is to have his/her results confirmed by repetition by others. If it isn't reproducible than it isn't believable. But wrong conclusions.... Record your mistake in the results and talk about it in the conclusion/examination of data.

Is it true that scientist who performs an experiment has no idea what the outcome of the experiment is going to be?
Many times, the scientist has a fair amount of confidence that the experiment will perform according to the prediction.
What do you call a scientist that runs an experiment three times?
Careful
How do you determine experimental probability?
You conduct the appropriate experiment repeatedly and calculate the proportion of times that the specified event occurs compared with the total number of experimental trials.You conduct the appropriate experiment repeatedly and calculate the proportion of times that the specified event occurs compared with the total number of experimental trials.You conduct the appropriate experiment repeatedly and calculate the proportion of times that the specified event occurs compared with the total number of experimental trials.You conduct the appropriate experiment repeatedly and calculate the proportion of times that the specified event occurs compared with the total number of experimental trials.

When scientist do tests more than once?
Repeating or replicating a test or experiment can reduce the chance for errors. For example, if you flip a coin once and get heads, you could conclude that you will always get heads when you flip the coin. If you flip the coin many times, you should realize the outcome is much closer to 50% of the time heads and 50% of the time tails. After one scientist does an experiment, a second scientist may want to run a similar test to determine whether the conclusions made by the first scientist were in fact accurate. Using the same or a similar method, anybody should be able to replicate the results.
What happens when scientist have to redo an experiment?
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
What is the experimental probability of rolling a 2 on a number cube rolled 50 times?
Conduct the following experiment: Roll a number cube 50 times. Count the number of times you roll a 2. Divide that number by 50. That is the experimental probability. The answer that I might get may well be different to yours. And if you do you experiment another time, the answer is likely to be different.
How does the atmosphere's temperature effect the burn rate of a candle?
the atmospheres temperature changes the candle in size. i am a scientist, and have done this experiment many times. believe in my answer, for my answer is the ultimate truth.
The same experiment was conducted 8 times. How many times should the results have been similar for them to be valid?
8 - Apex
