A quick statistics question

[lovingboth]

Something I'm reading sometimes gives significance levels like this: 'p<0.01' and sometimes like this: 'p.<0.01'.

Dodgy typesetting or is there actually a difference?

Dodgy typesetting - no dot

I've been teaching stats for 10+ years and I must admit I've never seen "p.". Of course that may partly be that I don't /expect/ to see "p.". Even so I still think its a typo. "p", of course, in the variable conventionally used to represent the probability of something (though is some circumstances we also use the greek pi) but we don't usually regard variable names as abbreviations.

Dodgy typesetting was my thought, but as they use it consistently in some parts and consistently not in others, I was wondering.

It's by more than one person, so it could be someone showing they don't really know what they're talking about :)
