Answer:

The answer is 6.

Step-by-step explanation:

Note that the formula of variance for calculation purpose is

1

n

n

∑

i

=

1

x

2

i

−

(

1

n

n

∑

i

=

1

x

i

)

2

where

n

is the total number of values in the given data set.

In your given data we have

n

=

5

and the values of

x

i

's are

{

1

,

2

,

3

,

4

,

5

}

.

So, your variance

=
