Short answer: if your p value is less than your critical it's sig. Long answer: you need to read around this to gain understanding. Here's a link to a wiki articcle that will get you started (LINK)I don't know how to tell if a value passes the critical region or not. What does it mean if something is significant at the .01 level? How do I tell? What does it mean for a value to be less than the critical?

There is no such thing as .000 p value (except in theory). .000 in SPSS is due to rounding, say .00001 becomes the .000And what does a .000 significance level mean? That is on a lot of SPSS outputs and I don't know what it means.
