Charlie: sqrt(((95–91.67)² + (88–91.67)² + (92–91.67)²) / 3) = 3.51 Then, we subtract the mean and divide by the standard deviation for each score: Normalized scores: Alice: [(85–85)/7.02, (92–85)/7.02, (78–85)/7.02] = [0, 1, -1] Bob: [(60–65)/5.00, (70–65)/5.00, (65–65)/5.00] = [-1, 1, 0] Charlie:
