In extremely broad terms, statistical significance means that it’s likely that something is happening, while clinical significance verifies to what extent that thing is happening.

Statistical significance for the difference between two independent groups (unpaired) - proportions (binomial) or means (non-binomial, continuous). Information on what a p-value is, what is statistical significance, how to interpret a low p-value / significant result, explanation of commmon misinterpretations. One-tailed vs. two-tailed tests. If you’ve ever seen a news story about a scientific study, you’ve probably heard something like “statistically significant results.” More likely than not, wh We call this statistical significance.
