Many trials are taken in an experiment as a way to limit experimental error. For example, if you are timing how long it takes a ball to roll down an angled track, as a human being you might release the ball at the wrong time, or push the stop button on the timer early or late. By running multiple trials and averaging the results, these errors should balance themselves out and give a better result.
There is no set number of trials considered universally acceptable in an experiment. The number of trials needed can vary depending on the nature of the experiment, the desired level of statistical significance, and other factors. Typically, researchers aim for a sufficient number of trials to ensure reliable results.
An experiment's results are considered reliable when they can be consistently reproduced in multiple trials by different researchers. Additionally, when the experiment's methodology is sound, and the results can be verified by peer review and further experimentation, the reliability of the findings is strengthened.
Ensure that measurements are taken carefully and consistently, minimize sources of error by controlling variables, use appropriate equipment calibrated regularly, and take multiple trials to calculate an average for more accurate results.
Repeating an experiment helps to ensure the results are reliable and not just due to chance. Consistent results across multiple trials strengthen the conclusions drawn from the study and increase confidence in the findings.
Results that are consistent or reproducible across multiple trials are considered reliable in an experiment. These results should not change regardless of any variations in experimental conditions or procedures. Additionally, results that align with the expected outcomes based on the hypothesis and theoretical framework also typically remain constant.
Trials are the amount of times a certain experiment is repeated.

The number of trials and sample sizes generally increase the accuracy of the results because you can take the average or most common results in the experiment
Repeated trials of said experiment.
so your answer is accurate
how many times did you trial your experiment, for each test you did
So the experiment's results are more reliable
If it is the same experiment attached to link, you would need only 1 trial each unless you want to retry if there is more grain or shape distribution. There is no requirement for how many time in repeating experiment since it is observation experiment not measuring experiment.

Completing many trials of an experiment is crucial for ensuring the reliability and validity of the results. It helps to minimize the impact of random errors and variability, allowing researchers to identify true patterns and effects. Additionally, repeated trials provide a more comprehensive understanding of the phenomenon being studied, increasing confidence in the conclusions drawn from the data. Ultimately, a larger sample size enhances the statistical power of the experiment.
