“…In addition, while continuous measures of skin tone (e.g. 1-very dark, 2-dark, 3-medium, 4-light, and 5-very light) are common in previous research (see, for example, Gullickson, 2005; Thompson and Keith, 2001;Keith and Herring, 1991;and Hughes and Hertel, 1990), they would not register the non-linearities shown in Table 2 (see also Hersch, 2006 andGoldsmith, Hamilton, andDarity, 2006). Table 3 shows the results using a continuous rather than categorical measure of skin tone.…”
