If you have had reports from us before, you may have seen tables which bear some coded markings, like this:
* p < 0.05, ** p < 0.01, *** p < 0.001 (Chi-squared)
Asterisks show where the differences seen between figures are statistically significant, that is, unlikely to be due to chance. Just how unlikely is shown by the number of asterisks, where *** says that fewer than one in a thousand similar studies would yield a result as different as this by chance alone.
