hlsmith: I was talking about linear regression. So lets take a concrete example:

So a year increas in education for someone who is white (black = 0) and starts with highschool (grade = 0) is associated with an 59 cents increase in hourly wage. This effect education increases by 3 cents for every year more education.

A black person with highschool can expect 83 cents less in hourly wage than a with person with highschool.

The effect of a year more education for someone who is black and starts with highschool is 22 cents larger than that effect for a white person. So a year more education if a black person starts with high school is associated with a 59+22 = 81 cents increase in hourly wage. Since there I included no interaction effect between age^2 and black, this effect of education increases by 3 cents for every year increase in education, just like it did for white persons.

A white person (black =0) with highschool (grade=0) can expect 7.09 dollars an hour.

I do look at the coefficients and interpret them, but I also look at graphs.
