The standard deviation measures the amount of variability or dispersion of a set of data. In Group A, the scores are relatively close together, with only a range of 2 points from the lowest to the highest score. In contrast, Group B has a wider range of scores from the lowest to the highest, resulting in a higher standard deviation. Therefore, the statement is true.
