If the difference in a measured behavior is so small between experimental groups that it could be caused by a chance fluctuation, then we would say that the result

A) failed to reach statistical significance.
B) reached statistical significance.
C) was reliable between groups.
D) established a cause-and-effect relationship.

Statistical Significance

Statistical significance is a measure indicating the likelihood that a result from data analysis is not due to chance, usually determined through a specific threshold value or p-value.

Chance Fluctuation

Random variations in data or processes that are not attributable to any specific cause, often observed in statistical analyses.
