Determine the standard deviation of the data below. (1, 2, 3, 4, 5)

a) √2
b) 3
c) 2

sqrt(2)

Step-by-step explanation:

1. Find the mean.

Mean=1+2+3+4+5=15/5=3

2. Subtract each number by the mean and square the value.

1-3=-2^2=4

2-3=-1^2=1

3-3=0^2=0

4-3=1^2=1

5-3=2^2=4

3. Add the values in step 2 then divide by amount of numbers.

4+1+0+1+4=10/5=2

4.Square the value in step 3 and that is the answer.
