"The statement’s six principles, many of which address misconceptions
and misuse of the p-value, are the following:
1. P-values can indicate how incompatible the data are
with a specified statistical model.
2. P-values do not measure the probability that the studied hypothesis
is true, or the probability that the data were produced by random chance
alone.
3. Scientific conclusions and business or policy decisions should not be
based only on whether a p-value passes a specific threshold.
4. Proper inference requires full reporting and transparency.
5. A p-value, or statistical significance, does not measure the size of
an effect or the importance of a result.
6. By itself, a p-value does not provide a good measure of evidence
regarding a model or hypothesis.
The statement has short paragraphs elaborating on each principle."
