Question

If the variance of a variable is 16​, what is the standard​ deviation?

Answer 1

Answer:

Standard deviation=4

Step-by-step explanation:

Standard deviation = square root of variance

Standard deviation=√variance

Variance=standard deviation square

Variance=standard deviation^2

From the question

Variance=16

Standard deviation=?

Standard deviation=√variance

=√16

=4

Standard deviation=4

check:

If standard deviation=4

Variance=standard deviation^2

=4^2

=16

Therefore,

Standard deviation=√variance

Answer 2

$4$

Variance

• The variance is a measure of how much each point deviates from the mean on average.
• The standard deviation of a set of numbers is the distance between them and the mean. (The mean is the arithmetic average of a given group of integers.)
• To compute the standard deviation, take the square root of the variance.

Variance of the variable $=16$

Standard deviation $=\sqrt{16}$

                                $=\boldsymbol{4}$
