Thank you for the opportunity to help you with your question!

Arrange in order -3 0 1 2 3 6

Range = highest -lowest

6-(-3)=9

Variance= find the mean first

mean =1.5

1.5--3=4.5^2=20.25

1..5-0=1.5^2=2.25

1.5-1=0.5^2=0.25

1.5-2=0.8^2=0.64

1.5-3=-1.5^2=2.25

1.5-6=4.5^2=20.25

Add all of them and divide by 6, the number of population

=7.7

std deviation=2.7

Std Deviation=

Please let me know if you need any clarification. I'm always happy to answer your questions.

find the square root of variance to get the std deviation

i hope you have understood

W e start by finding the mean after which we subtracts mean from each population and then you do the square after which you can add all the squares and then calculate the total . The total of the squared are then divided by the number of population which in this case is 6,
