Why are repeated trials important in scientific investigations and what should you do if repeated trials give very different results?
We know that many phenomena are quite variable. The weather is not the same every day. One person does not necessarily act the same way or have the same biological features as another person. Some individuals might be typical of their species, while others might be unusual in some way. So, if you are investigating some particular phenomenon, you want to make sure that the results that you got are normal or representative results, rather than anomalous results. Even aside from the variability of nature, there is also the factor of the imperfection of scientists. Scientists can also be sloppy, and can make mistakes. You might have used the wrong chemical, mislabeled something or misread a label, and so forth. We can never simply assume that any given experiment was done correctly. So, by doing something repeatedly, we can be more confident of the result. We confirm the result by getting it more than once.
If, however, we do repeated trials and get different results, that is an interesting observation and it becomes necessary for us as scientists to find out the reason for these varying results. There is something we did not notice, something that is not the same, or something that is more unpredictable than we thought it was. Maybe we thought that all of our mice were the same, but it turns out that we are actually dealing with two different species of mice, and they have significantly different biological traits. Whatever the problem is, we have to track it down and identify it, otherwise we will never be able to understand the results of our experiment.

Why is it important that science investigations be repeated What happens when other scientists achieve different results when repeating an investigation?
1. Its important because if you repeat you'll get consistent results. 2. That means if a scientist gets different results it means they did something wrong in the experiment
How scientific theory developed?
Many different experiments are performed and repeated.
Why is it necessary to use careful and systematic methods when carrying out scientific investigations?
The scientific method requires carefully controlled environments and closely monitored methods because the experiment must be able to be repeated with similar results by others.
Describe why it is important that scientific experiments be repeated?
because the are diffident student every year......
Why it is important that scientific experiments be repeated?
To test if something has been done wrong or out of order. Id repeated data can be well-defined.

Why it is important that scientific investigations be repeated?
This is important to ensure that one set of results is not a "fluke". Ie, if you did an experiment once, the results may have been caused by an extraneous variable, this is a condition which occurs that is beyond the scientists control. Therefore, to ensure the results are reliable, the test must be repeated, usually with a few things changed in the method each time. The more results that match from different tests, the more accurate the results are likely to be.
What do scientists do to ensure that their investigations can be repeated and obtain the same results?
they publish their hypotheses on the internet

What is a scientific law based on?
A scientific law is based on many repeated correct experiments.
Why is it necessary to perform repeated investigations in order to test a hypothesis?
Repeated investigations are essential to test a hypothesis because they help ensure that the results are reliable and not due to random chance or specific conditions. By conducting multiple trials, researchers can confirm the consistency of their findings, identify potential variables that may affect the outcome, and strengthen the overall validity of the hypothesis. This process also allows for peer verification and contributes to the body of scientific knowledge, ensuring that conclusions drawn are robust and applicable in broader contexts.
Why might the results of repeated investigations differ?
The results of repeated investigations might differ due to variations in experimental conditions, such as changes in environmental factors, measurement techniques, or sample sizes. Human error in data collection or analysis can also lead to discrepancies. Additionally, inherent variability in biological or physical systems may produce different outcomes even under similar conditions, highlighting the complexity of the phenomena being studied.
What is meant by validated evidence?
(In terms of physics and scientific prospect) A theory news to be checked or 'validated' by experiments that can be repeated by different people. Regards, Amir
