Statistical Significance
Captions available
The idea
A statistically significant result is one unlikely to have been produced by chance alone.
In practice
A difference between two groups reported as unlikely to be a chance finding.
Where people slip
Statistical significance is a statement about chance. It says nothing about the size of the difference and nothing about whether that size matters to a patient.
