Question

renald completed only one trial of his experiment. what effect will this most likely have?
the results are more likely to have errors.
the results are more likely to be precise.
the experiment will be harder to replicate.
the experiment will be easier to replicate.

Explanation:

In scientific experiments, multiple trials are used to reduce errors and increase the reliability of results. Completing only one trial means there's less data to identify and account for random errors or anomalies. So the results are more likely to have errors. Precision comes from consistent results across multiple trials, so one trial doesn't increase precision. Replicability depends on the experimental procedure, not the number of trials done by the original experimenter, so one trial doesn't make it harder or easier to replicate.

Answer:

A. The results are more likely to have errors.
