What is Statistical Significance?
A measure of confidence that a difference in test results is real and not just random chance.
Why It Matters
Without statistical significance, you might make product decisions based on random fluctuations rather than real differences.
Real-World Example
An A/B test showing version B has a 5% higher conversion rate, with 95% confidence this is not due to chance.
“Understanding terms like Statistical Significance matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
