I'm note completely sure I know what you're referring to but if you are talking about the x-axis for the figure in the blog (Figure 2 in the article), the lowest value is 400-1200. In the article the authors write: |The regression results imply that a student with a (hypothetical) SAT |score of 0 can expect a 1.19 units lower grade from a Republican |professor than from a Democratic one, while for a student with a SAT |score of 700 (the lowest score in the sample) the difference is 0.54 grade |units. In contrast, a student with a perfect SAT score of 1,600 can expect |a 0.30 units higher grade from a Republican professor than from a |Democratic one. So, their lowest SAT total score was 700. Their mean SAT score was 1359 with SD= 116 (see Table 2).which make a score of 700 an outlier (z= -5.68). I haven't looked at the raw data but I assume that the SAT score distribution is negatively skewed. -Mike Palij New York University [email protected] --- You are currently subscribed to tips as: [email protected].
