I'm not sure specifically what this 'stats novel' is about as the name is rather ambiguous. It could potentially be a novel that involves statistics in some way, like a story about a statistician or perhaps a fictional world where stats play a crucial role.
There's no way to tell if it's popular just from this title. It might be a niche novel that only appeals to a specific group of readers who are interested in stats - related stories. Or it could be a self - published work that hasn't gained much traction yet.
I'm not sure, actually. It could be a unique title chosen for artistic or thematic reasons that don't have a straightforward connection to the concept of a name.
Well, it really comes down to your settings. If your story is set to be visible to friends or if you've chosen to share it with them directly, they'll be able to view it. Otherwise, they won't have access.
