P

p-value

In statistics and A/B testing, a p-value indicates the probability that test results occurred by chance alone. A p-value of 0.05 or lower generally indicates statistical significance, meaning the differences observed are unlikely to be due to random variation. Understanding p-values helps determine whether web performance changes result from actual improvements or just natural variation.
