In the article “Association of UV index, latitude, and melanoma incidence in nonwhite populations: US surveillance, Epidemiology, and end results (SEER) program, 1992 to 2001” published in the Archives of Dermatology (Eide and Weinstock, 2005), the authors report a correlation of ???? = −0.85 between melanoma incidence and the latitude where an individual lives for white men and a correlation of ???? = 0.53 for black men. On the basis of this information does the incidence of melanoma appear to increase or decrease with an increase in latitude for

(a) white men?

(b) black men?
