Which set(s) has the largest standard deviation?

1. Set 1 consisting of 10 digits

2. Set 2 consisting of 10 first positive consecutive even numbers

3. Set 3 consisting of 10 first primes

set 1

set 2

set 3

sets 1 and 2

none

I did not understand why Set 1 is not the correct answer especially when nothing is known about Set 1. The digits in Set 1 can be even farther than the set consisting 10 forst primes. I think I am missing something?

sd is the DISPRESION of the terms....

the distance between SET 1 and 2 is fixed therefore the dispression is fixed....

but for set 3, the distance between terms vary, therefore more dispression therefore more SD

hope it helps
