Question

increasing the number of trials
why does increasing the number of trials increase confidence in the results of the experiment?

Explanation:

In experimental design (a concept in Natural Science, especially in scientific method), increasing trials reduces the impact of random errors or outliers. With more trials, results tend to approach the true underlying pattern (due to the law of large numbers), making the outcome more reliable and thus increasing confidence.

Answer:

Increasing the number of trials reduces the influence of random chance (e.g., outliers, short - term fluctuations) on the results. As the number of trials grows, results are more likely to reflect the true relationship or phenomenon being studied (supported by the law of large numbers, where larger sample sizes/trials lead to results closer to the theoretical or actual underlying pattern), so confidence in the experimental results increases.
