Set A = {15, 19, 20, 21, 25}: The values are relatively close to each other, with most values clustered around the mean (which is approximately 20). This indicates a smaller spread in the data.
Set B = {15, 18, 20, 22, 25}: The values are also relatively close, but there is a wider spread. The lowest value (15) and the highest value (25) are further apart compared to Set A.
Since the standard deviation measures how much the values deviate from the mean, and Set B has a slightly wider range of values (with 18 and 22 being further from the center), Set B will have a greater standard deviation than Set A.
