If sample variance is computed by dividing SS by df = n – 1, then the average value of the sample variances from all the possible random samples will be the population variance

And if we take the average value of the sample variances from all the possible random samples we will get the population variance:

So then the best answer for this case would be:

The average value of the sample variances from all the possible random samples will be exactly the population variance

Step-by-step explanation:

For this case we can define the sum of squares with this formula:

Where:

And we can find the sample variance with this formula:

And if we take the average value of the sample variances from all the possible random samples we will get the population variance:

So then the best answer for this case would be:

The average value of the sample variances from all the possible random samples will be exactly the population variance
