in science it means to do it again and again to see the results
That its wrong (false).
If you repeat the experiment and you get different results, then the accuracy of your first trial is not correct.
The requirements are that there are repeated trials of the same experiment, that each trial is independent and that the probability of success remains the same.
Trial and error is a fundamental method of problem solving. It is characterized by repeated varied attempts which are continued until success.SIMPLIFYING FRACTIONSsimplifying fractionsWhen you try to factor a polynomial the most taught method is trial and error. My manipulating the factors you see which terms and coefficients answer the question.
Edward Thorndike is a behaviorist who proposed the Law of Effect, suggesting that learning occurs through trial and error. He believed that behaviors resulting in positive outcomes are more likely to be repeated.
There are occasions where the probability distribution function (pdf) has to be obtained empirically (experimentally). However, it is possible that it is expensive (in time or money) to carry out repeated experiments. In such a case, it can be useful to build a mathematical model that simulates the trial. Input random numbers and the model outputs the result of the trial. In this way it is easier to carry out repeated trials and so generate the required pdf.
Tossing a coin ten times is a [repeated] experiment or trial. It is neither empirical nor theoretical probability.
If the jury cannot decide whether the accused is guilty or not, the case can be repeated but with a different selection of jurors.

0.225 Repeated, 0.225, 0.25 Repeated and 0.25.
Repeated Trails are the number of trails done during a scientific experiment with the purpose of getting a more accurate result.
When the answer was repeated, she understood it better.
