What it means

In an A/B test one group sees the original and another sees a variant, and their results are compared. Random assignment lets you attribute the difference to the change.

Run it long enough and with enough traffic, or the result will be noise.

Why it matters, with an example

It separates a change that helped from a month that was simply better.

For example: Show the old headline to 5,000 visitors and the new one to 5,000. 8%), the next question is whether that gap is larger than chance.
