If the results get ridiculously high or low/or if they needed to do more trials/or if they missed some procedures
To see if thier answer is the same
Scientists record experiments in trials.They repeat experiments over and over again so they can find averages.Also,experiments in different conditions,called varibles,could change.But the main reason is the outcome would change
Scientists repeat experiments to test whether results are consistent and reliable.
Scientists use data from controlled experiments to minimize the influence of outside factors, in order to isolate the effect of the variables they are studying. This helps to establish a cause-and-effect relationship between variables and ensures the results are more reliable and accurate.
Repeatability...multiple experiments conducted under identical conditions serve to prove the results of the initial experiement.
The run the experiments over and over again, looking for anything that may have gone wrong to give them that outcome. They also test variables to see how changing them affects the outcome. Also, research teams that are independent from the original team usually try to verify the outcome to verify the integrity of the experiment.
Well first of all they would because sometimes science gets hard if you use the same thing over and over again so they must switch every now and then and plus i had this question on my test and got it right.
There have been various experiments measuring the ozone layer. The ozone over the poles is seen to have depleted.
once. as Einstien once said; "insanity is doing something over and over again and expecting different results".
They used to share results because sharing allowed other scientists to build on what they had done and thus science and knowledge would be advanced. Unfortunately, desire for personal wealth (greed) is taking over and scientists are not sharing results as liberally as they did in the past.
"Mistake," or some other word meaning essentially the same thing.
Experiments are done all over the world. The place that most experiments are done is in America.
