Question

If SD = 4 cms, find variance.​

Answer 1

Answer:

$variance = {(sd)}^{2} = {4}^{2} = 16$

Answer 2

Answer:

The variance is 16 cm²

Step-by-step explanation:

Given SD = 4 cm

SD is the standard deviation.

We need to find the variance from the given SD.

We know that variance is the square of the standard deviation.

i.e. if standard deviation is represented by σ

Then, Variance = σ²

Therefore, substituting the values, we get,

Variance =  4²

               = 16

Therefore, the variance is 16 cm²
