# Thread: p value?

1. ## p value?

I have several "p values" with a value of 0.000 in SPSS. A reviewer in a paper I submitted is repeatedly asking for EXACT p values and not like <0.001.

How do i find out the exact p value.???

Double click on the value, you will see that the actual computed p-value becomes visible.

Because your other post was a double-post, it has been deleted.

even if you use your pointers to go right?

Here's another way:

You will need to know which distribution to use!
t-test -> students T
ANOVA -> F-distribution
ect ect

5. when i double click the 0.000 p value in spss 14 it gives me this: 1.458305252439e-017

does this mean that there are 17 zeros after the decimal point...

.. like: 0.0000000000000000145
