Question

enald 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, repeating trials (multiple trials) helps to reduce random errors and increase the reliability of results. If only one trial is done, there's a higher chance that the result is affected by random factors or errors, so the results are more likely to have errors. Precision comes from consistent results across multiple trials, so one trial doesn't make results more precise. Replicating an experiment refers to other scientists doing the same experiment, and the number of trials in the original experiment doesn't directly make it harder or easier to replicate (replication is about following the procedure, not the number of trials done by the original experimenter). So the correct option is the one about results being more likely to have errors.

Answer:

A. The results are more likely to have errors.
