Above is a regression of men's monthly earnings in dollars as a function of their years of education, their IQ score in "points", their Knowledge of the World of Work (KWW score in points (a measure of their knowledge of how occupations work), their years of work experience (exper), whether they are Black, and their parents' education (fea and meduc).

Above is a regression of men's monthly earnings in dollars as a function of their years of education, their IQ score in "points", their Knowledge of the World of Work (KWW)
score in points (a measure of their knowledge of how occupations work), their years of work experience (exper), whether they are Black, and their parents' education (feduc
and meduc).
How would you interpret the coefficient on IQ?
For each additional IQ point, men earn about $1.20 more per month, controlling for education, knowledge of the work world, years of experience, whether they're
Black, and parents' education.
For each additional IQ point, men earn about 3 percent more per month, controlling for education, knowledge of the work world, years of experience, whether they're
Black, and parents' education.
For each additional IQ point, men earn about $2.64 more per month, controlling for education, knowledge of the work world, years of experience, whether they're
Black, and parents' education.
For each additional IQ point, men earn about $3 more per month, controlling for education, knowledge of the work world, years of experience, whether they're Black,
