Why is it important for experiments to be able to be repeated?

Being able to repeat experiments is important in many fields of science. The main reason that it is important for experiments to be able to be repeated is so that the same scientist, or other scientists, can conduct the exact same experiments and see if they are able to obtain the same results. This helps to validate that the previous findings are correct and did not occur due to some random factor outside of the experimental set up. Repeating experiments and getting the same results leads to further support of the original findings. Validation of repeated experiments is very important in all fields, but is especially important in fields like medicine. For example, if a group of doctors or scientists discovers that a certain drug can help cure an illness, it is important the experiments are repeated, and the same results are obtained before that particular drug is administered to the general public. Hope this helps!
