TRUE OR FALSEExperiments should be repeated for more than one trial to verify your results
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Most teachers want you to repeat your experiment a minimum of three times. Repeating your experiment more than three times is even better, and doing so may even be required to measure very small changes in some experiments. In some experiments, you can run the trials all at once.

Detailed explanation-2: -Repeated trials are where you measure the same thing multiple times to make your data more reliable. This is necessary because in the real world, data tends to vary and nothing is perfect. The more trials you take, the closer your average will get to the true value.

Detailed explanation-3: -For most types of experiment, there is an unstated requirement that the work be reproducible, at least once, in an independent experiment, with a strong preference for reproducibility in at least three experiments.

Detailed explanation-4: -When we do experiments it’s a good idea to do multiple trials, that is, do the same experiment lots of times. When we do multiple trials of the same experiment, we can make sure that our results are consistent and not altered by random events. Multiple trials can be done at one time.
