I would assume it would be something of this nature...however it doesn't matter for those taking it this year and on, as the NBDE is moving to Pass/Fail, so you won't know what your exact score even is. Aim for PASS!
Just take a look at the current years NBDE scores and their average DAT scores when they entered dental school. This will vary from year to year though.
I forgot who was the one who posted the statistics, but in it, the common theme was those that did well on the DAT ended up being more successful in dental school and scoring better on the NBDE.
