In a controlled experiment how do the number of trials and sample sizes effect the results?
The number of trials and sample sizes generally increase the accuracy of the results because you can take the average or most common results in the experiment
What is controlled in a controlled study?
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group. A control experiment is designed to check or correct the results of a previous experiment. It does this by removing the variable or variables operating in the other experiment. The comparison obtained is an indication or measurement of the effect of the variables concerned
In an experiment to see the effect sleep has on memory tests one group got eight hours of sleep a night and the other group got five hours a night. In this experiment what is the dependent variable?
The results of the memory test
Why do scientists run control experiments and repeat their tests several times?
To make sure they did it right and that their results can be replicated.Scientist do experiments more than once to make sure they are accurate in measuring or finding out, so basically to make sure it is correct in case they have different answers. Normally they check at least 3 times.
What is the definition of control in science?
Control in science is something that can be used for comparison to determine the magnitude of an experimental effect. For example in a control group either nothing is done or a fake version of the experiment is performed to determine a "baseline". The results of the control experiment and the real experiment can be compared. This process helps eliminate the experimenter expectations effect, making the conclusions more objective. Note: controls are rarely needed outside the field of biology.

Why would measurements effect an experiment?
Because the measurement usually requires putting the measurement device in the experiment. Just observing an experiment effects it because you are interpreting the results.
What is the effect of increasing the mass on the experimental value of the acceleration due to gravity?
This appears to be a question about an experiment. We can't tell you what the results of the experiment were because we weren't there.
In flowers for Algernon what is the name of the experiment in the short story?
The experiment in "Flowers for Algernon" is called the "Algernon-Gordon Effect" experiment, which aims to enhance intelligence through surgical manipulation and the use of a new technique to improve cognitive abilities.
In an experiment?
Ensure that all variables are controlled except for the one being manipulated to determine its effect on the outcome. Accurately record data and replicate the experiment to verify results. Analyze findings to draw valid conclusions and consider any limitations or biases that may have influenced the results.
Why is it important that an experiment be repeatable?
to get the best and actual result.maybe sometime there is a very small factor that may effect our result. to get the best and actual result.maybe sometime there is a very small factor that may effect our result.
How does the manipulation of an independent variable during a scientific experiment allow a scientist to find a cause and effect?
The manipulation of an independent variable during a scientific experiment allows a scientist to find a cause and effect relationship between variables. This is because the manipulation changes the results and measurements.
Differences between anomalous zeeman effect and normal?
normal zeeman effect occurs in strong magnetic field while anamolous zeeman effect occur in weak magnetic field

Why does changing materials effect your results during an experiment?
Blowing up a balloon with a helium tank, then blowing up a different balloon with your mouth will make a difference in the outcome of your experiment. It'll most likely give you more sources of error.
What should the classical experiment provide the researcher with?
A classical experiment should provide the researcher with reliable and valid data to test a hypothesis. It should allow the researcher to establish cause-and-effect relationships and draw meaningful conclusions based on the results.
