Question

If the standard deviation of the data values in a sample is 17, what is the variance of the data values

Answer 1

std dev = sqrt of variance

hence variance would be 17^2= 289

Answer 2

The variance of the data values is 289.

What is variance?

Variance can be defined as the square of standard deviation.

To calculate the variance of the data values, we use the formula below.

Formula:

• σ = S.D².............. Equation 1

Where:

• S.D = Standard Deviation of data values
• σ = Variance of the data values.

From the question

Given:

• S.D = 17

Substitute into equation 1

• σ = 17²
• σ = 289

Hence, the variance of the data values is 289.
