P-value
Definition
The probability of obtaining results at least as extreme as the observed results, assuming that the null hypothesis is true. A p-value below the significance threshold (usually 0.05) suggests the results are unlikely due to chance alone.
Example
A p-value of 0.03 means there is a 3% probability the observed difference occurred by chance.
