strange p value

[Aron Arnold]

Hello,
I wondered if someone could help me.
When I run a Mann-Whitney U test, I get this strange p value: "7.655e-3"
When I add or delete items from my Excel spreadsheet and run the test in exactly the same way, I get a correct value. But when I run it with all the data that I have to analyse, I get this 7.655e-3.
Could someone tell me what I'm doing wrong?
Thank you in advance :)
All the best,
Aron

7.655e-3 is the way SOFA (and most programming languages) does
scientific notation; it’s the same as 7.665 times ten to the -3. As
you can see, I can't type a superscript in this email; 7.665 x 10 ^ -3
is as close as I could get. That is why SOFA and programming languages
use the "e" notation (think of the "e" as standing for "tens
exponent") -- to get around the problem of not having superscripts on
old-style computer terminals and printers.

So, 7.665e-3, or 7.665 times ten to the -3, is 0.007665.

Sorry about the mistype of 7.655 as 7.665 in a couple of places. I
need new glasses :)

Thank you so much for your answer!!!
As I'm not that familiar with statistics software I didn't know this was a conventional way of encoding exponents.
So that's great new - my p value is definitely smaller than 0,05 :)
