Question

if the standard deviation of the data values in a sample is 19, what is the variance of the data values?

Answer 1

Answer: The answer is 361.

Step-by-step explanation: We are given that the standard deviation of a data is 19 and we are to find the variance of the data values.

we know that the variance of a data is the square f the standard deviation of the data values, so if the standard deviation is given to be 19, then the variance will be

`V=19^2=361.`

Therefore, the variance of the data values will be 361.

Thus, the answer is 361.

Answer 2

Variance = square of standard deviation. = 19^2 = 361.
