The outcomes must be repeatable because if the outcome keeps changing, then something must have changed during one of the experiments, giving you the different outcome.
The word repeatable means that it can occur again. In the case of a scientific question, you must be able to reproduce the experiment more than one time to prove it's not just a one-time occurrence.
So you can see it better
The study of physics, and indeed of any science, is thoroughly dependent on accurate and repeatable measurements. These measurements must be repeatable not only by one scientist on many occasions, but also my many scientists. In order for this to happen, for measurements to be repeatable, all the scientists must be using accurately standardized units of measure. Imagine what would happen if my meter and your meter were different, so that when I say one meter it is equal to your 99 centimeters? Answer: we really couldn't do any science because our measurements would not be repeatable. This is not to say that everybody has to use the same units. I can measure in inches while you measure in meters, as long as my inch is always equal to 0.0254 of your meters. But if either my inches or your meters vary from this then we are both out of luck.
precison
A regular, repeatable portion of a dimension.
They must be repeatable
The scientist must propose an idea and document it with experiments that prove it. The experiments must be repeatable by others and the same result must be obtained by them
Apex Experimental results are not reliable if they are not repeatable.
Science relies on repeatable, redundant results from experiments in order to consider it valid.
C. Repeatable
Science is the study of the universe: its life, its composition, and the physics that guide the universe. However, to be strictly scientific, a scientist must learn through the process of asking questions, answering them through scientific experiments, and his or her results must be repeatable.
outcomes
Repeatable
It is only science if it can be repeated, so yes, experiments do need to be repeatable in order for something to be proven. The results of the experiment should be comperable if something is to be learned.
theoretical
Theoretical probability.
Yes it is true
