  1. On the Multidimensional Scale of Perceived Social Support, the mean of a university student sample was 5.80, with a standard deviation of 0.86. For a student who scored 6.2 on the scale, what is the Z-score? The Z-score is ______________.<\/li>\r\n \t

  3. On the Multidimensional Scale of Perceived Social Support, the mean of a university student sample was 5.80, with a standard deviation of 0.86. For a student whose Z-score is 0, what is the raw score? The raw score is ______________.<\/li>\r\n \t

    1. Two siblings wish to compete for bragging rights on who performed best on their standardized test \u2013 but one took the LSAT for law school and the other took the MCAT for medical school. Sarah scored 163 (M<\/em>=151.88, SD<\/em>=9.95), but Rachel scored 510 on the MCAT (M<\/em>=500.9, SD<\/em>=10.6).

      2. Assuming that scores on a creativity measure are normally distributed, with a mean of 90 and a standard deviation of 10, between which values do the middle 50% of people score?
