The results are in! And the groups have different numbers

What does the "p" value mean?
The p-value is the probability of getting results like yours by pure chance:
- A large p-value (like 0.25) means the difference is likely just random variation
- A small p-value (usually 0.05 or less) means the difference is likely significant, something real may be going on!
