Definition
A measure of confidence that a result observed in an experiment is real and not just due to random chance.
Why it matters for growth
Without statistical significance, teams risk making permanent product decisions based on noise, which wastes engineering effort and erodes trust in data.
Example
A team waits until a test reaches 95% statistical significance before declaring the new pricing page a real winner.
