Answer 1

Answer #1

The standard deviation tell us how deviated the data is from the mean. If it is more deviated, then the standard deviation is high and vice-versa.

Here, we can clearly see that group 2 numbers are closer to each other with a gap of 1 whereas in group 1, the values are far with a gap of 10.

Hence, Group 2 has a smaller standard deviation.

Option A is the right answer.
