Question: 1. A behavioral scientist measures attention in a sample of 31 participants. To measure the variance of attention, she computes SS = 120 for this sample.
(a) What are the degrees of freedom for variance?
(b) Compute the variance and standard deviation.
2. A student computes a variance of 9. Will the standard deviation differ if 9 is the value for a population versus a sample variance? Explain.
