A standard score (z-score) indicates how many standard deviations an element is from the mean. A score of 1.9 (A) is well above average, likely an A. A score of 0 (D) indicates the mean, which could reasonably be a C, as it's in the middle of the grading scale. Scores of 0.7 (B) and -1.6 (C) would not typically result in grades D and B, respectively, given normal distribution assumptions.
