To display a number in a pivot table to more decimal places do the
1. Double-click on the table to start editing it.
2. Right-click on the cell (or cells) that you wish to change and select
3. On the 'Value' tab you can change the number of decimals to be
displayed. If you increase it high enough you will see the actual digits
in the p-value (eg, 0.000012).
However, if you are applying a manual Bonferroni adjustment you of
course know that the adjusted p-value can only be smaller than the
original. So if the original p-value (.000) was already less than 0.05
then the Bonferroni adjusted p-value will be as well.
