P value 0.00 means

WebIt's hard to imagine a scenario where a p-value like .0002 would be converted to anything other than .000, so saying P < .0001 is not a safe thing to do. To be honest, I tend to be conservative and round the p-value up in any ambiguous setting. So anytime SPSS reports a p-value of .000, I always report it as P = .001. There are two reasons for ... WebWhat this means is that the p-value < 0.0001(say 0.00001), there is a built-in function rounding your result up to 0.000 or truncating it at a fixed decimal. Cheers! Cite. 29th Aug, 2024.
