Statistical significance
What it is
Statistical significance usually means a result crosses a chosen statistical-testing threshold under a stated model.
What it does
The threshold is a convention rather than a measure of an effect's practical importance.
Research context and ingredient forms
A p-value does not by itself measure the size of an effect or the probability that a claim is true.
Using this information
Read the estimate, uncertainty, design, and number of analyses. A nonsignificant result is not proof that no meaningful effect exists.
