statistically significant
Probably not coincidence
Statistically significant describes a result unlikely to have occurred by chance alone.
In research, findings reach statistical significance when the probability of random occurrence falls below a threshold—typically 5%.
The term indicates the data probably reflects a real pattern rather than noise: The difference between groups was statistically significant.
Statistical significance doesn't necessarily mean the effect is large or practically important.
