The standard deviation measures how spread out the data is from the mean. As Group 1 has a much larger standard deviation than Group 2, it means that their data is more spread out and not as clustered around the mean as Group 2. Therefore, the scores for Group 1 differ most from scores for Group 2 in their standard deviation.
