Answer 1

Given

List of data

Find

Which of the following has the smallest standard deviation.

Step-by-step explanation

As we know standard deviation basically measures how the values are spread out.

without solving , we can tell whch has a smaller standard deviation.

the closer the values are to each other the smaller is the standard deviation.

so, in option 1 , the values are closest together.

Final Answer

Therefore , the correct option is 1.
