I think you should go for it, and offer to help the kid assure that the data is
applied in a valid fashion.  the kid appears to be a bit precocious, or
supported by a wiser adult, to be able to use "correlation coefficient" in that
manner.

I've had some very positive experiences with 6th - 8th graders (6 to 8th form,
I believe they say in the UK.  I don't know the term for Finland.) doing
designed experiments on things from popping popcorn to heat treating steel.

And yes, working from the application to the theory will attract more interest
and understanding than the other way around.  Every time.

Cheers,
Jay
