The ultimate p-value may then be a bit larger or smaller. However, a p-value much smaller than 0.01 will be rarely observed, because it would indicate that the study is overpowered. If the p-values can be assumed to follow a normal ...

WebWhen rounding, 3 digits is acceptable if rounding would change the significance of a value (eg, you may write P =.049 instead of .05). If P <.01, it should be expressed to 3 digits.
