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.

How many trials is considered to be acceptable in an experiment?
4
What is a constant in a experiment?
Constants are the things that are kept the same each time one of the trials in the experiment is repeated. For example, constants could include the amount of water used, the brand of effervescent tablet used, the type of water used, and the fact that the water was not stirred. As many outside factors as possible should be kept constant in an experiment so that the researcher can be sure that any changes that occur do so because of the independent variable.
What is a experiment on accuracy?
Accuracy is depended on how many "shots" you take to a certain target. If the "shots" are close to each other , you have good accuracy.
What safety precaution should you take when performing an experiment that involves electricity?
Always perform the experiment under adult supervision.
What are the Suggestion to improve the accuracy of the falling sphere viscometer experiment?
Limit variables. Use accurate measuring equipment. Use multiple trials to obtain data that can be averaged. Observe intently.

What are trials in an experiment?
Trials are the amount of times a certain experiment is repeated.
In a controlled experiment how do the number of trials and sample sizes effect the results?
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
What increases the validity of an experiment?
Repeated trials of said experiment.
Why do you have to have trials in an experiment?
so your answer is accurate
What does numbers of trials per test means?
how many times did you trial your experiment, for each test you did
Why are multiple trials important when carrying out an experiment?
So the experiment's results are more reliable
How many trials did you run for the sand experiment?
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.
What is the minimum number of trials for an experiment to be valid?
3
What probability is based on repeated trials of an experiment?
Experimental Probability
