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
sets 1 and 2
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
