What is called when scientists do their experimental tests more than once so they can reduce the effects of chance errors?
== ==
What else can I help you with?
Scientists do their experimental test more than once so they can reduce the effects of chance errors This is called?
average result is the result when you do a few times of the same experiment and get a few result then you average it.
Why is Sonny With a Chance called that?
I wonder that, too:) I guess it's because the girl, Sonny has a chance of becoming famous, so Sonny With a Chance- chance as in a chance at becoming famous... so it's kind of like Sonny With a Chance of being famous
What is the chance of a vaccine going wrong?
The chance of a vaccine causing harm is very low. Vaccines undergo rigorous testing in clinical trials to ensure safety and efficacy before they are approved for use. The benefits of vaccination in preventing disease far outweigh the risks of potential side effects.
Why are scientist using a placebo?
Scientists use a placebo to check that the variable they are changing actually is responsible for the results they see. It is like a control experiment, allowing you to compare the trial with it to see if there is any effect. It also counteracts the "placebo effect". For example, this is when someone taking a drug calims they "feel better" despite the drug not actually having any effect. Therefore, by giving some test subjects a placebo and some the drug being tested and not telling them which is which, you can eliminate the placebo effect from the test.
How much percent does it take so you know the experiment works?
You have to calculate the amount of error that can be expected in your experiment, and if the results exceed the experimental error, they can be considered to be meaningful. We would really have to discuss a specific experiment to see how this principle works.
What do the scientists do their experimental tests more than once so they can reduce the effects of chance errors this is called conducting?
Repeated Trials

Scientists do their experimental tests more than once so they can reduce the effects of chance errors.?
Yes? There is always a chance that experimental results happened by chance (something called a Type I error in Statistics which is bad, but over-emphasized). Replications (which are not done often enough) help protect us against such "accidental" effects because reproducing the results by chance is FAR less likely than just getting them once by chance. But reproducing REAL effects should be quite easy. Though if it is the same scientist, in the same lab, it is possible the results can be replicated even when they shouldn't be replicated, not by chance, but because of something systematic (dirty or faulty equipment, poor randomization, experimenter accidently communicates something to the participant, ...).
When scientisits do their experimental tests more than once so they can reduce the effects of chance errors this is called conducting?

What scientific discovery made by chance as opposed to the scientific method?
Penicillin was discovered by chance in 1928 by Alexander Fleming when he noticed that a mold called Penicillium notatum killed bacteria in a culture plate. This accidental discovery led to the development of the first antibiotic and revolutionized medicine.
What is a tool that helps scientists determine if a phenomenon occurred by chance or if it is connected to an experimental variable?
Repetition of the experiment.
Assumption that experimental results are due to chance alone is called?
null
Scientists do tests more than once to reduce chance of errors called conducting a what?
It is called repeated trials.
Why is replication important in experimental?
Observed results are less likely to be affected by random chance.
