Question

If the standard deviation of a data is 0.012. Find the variance.
Select one:
a. 0.00144
b. 0.0000144
c. 0.144
d. 0.000144​

Answer 1

Answer:

c)

Step-by-step explanation:

maybe but I am not sure, (╥﹏╥)

Answer 2

If $0.012$ is the standard deviation of the data, then the variance is $0.000144$ (option d).

Given,

The standard variation of the data is 0.012.

To Find,

The variance of the data.

Solution,

The method of finding the variance of the data is as follows -

We know that for a data set the variance is the square of the standard deviation i.e. if the standard deviation of a data set is σ, then the variance of the same data set will be $v=\sigma^{2}$ .

So the variance of the data is $(0.012)^{2}=0.000144$ .

Hence, if $0.012$ is the standard deviation of the data, then the variance is $0.000144$ (option d).
