I don't think that's correct. Barron's unusual, but I think most 13 year old boys would fall between 5'5" and 5'10", some above and below.
Heck, I was around 5'8' as were several friends. Don't remember any who were still only 52".
This chart still has the average girl at 13 taller than the average boy.

That can’t be right, can it? I wonder with so many of our school-age children now being Hispanic if that is pulling down our averages.
I think my husband and brothers had their growth spurts near 14. Husband was 5’11” at that age. I think one brother kept growing into his 20s.
