Final answer:
The concept illustrated by multiple scientists obtaining similar results from performing the same experiment is replication. Replication is important as it confirms the validity of the experimental results and is a cornerstone of the scientific method.
Step-by-step explanation:
The concept best illustrated by the situation where a scientist conducted an experiment and discovered that certain plants grow faster when given a particular amount of fertilizer, and another scientist getting similar results when conducting the same experiment is replication.
Replication refers to the process of repeating an experiment by a different individual or group, and obtaining the same results. This serves to confirm the findings of the original experiment. A closely related concept is repetition, which refers to the process of conducting the same experiment multiple times to ensure consistency in the results and rule out random chance. When different scientists can replicate the results of an experiment, it strongly suggests that the results are valid and reliable, reinforcing the integrity of the scientific method.
In contrast, precision refers to how close repeated measurements or results are to each other, whereas validity refers to the extent to which an experiment measures what it is supposed to measure. However, in this context, the repeated success in obtaining consistent results through replication is the central focus.
