Brent calculated that the sum of squared errors (SSE) for the variables is 267. The mean squared error (MSE) would be: A. 15.706. B. 14.831. C. 14.055.
The MSE is calculated as SSE / (n – k – 1). Recall that there are twenty observations and two independent variables. Therefore, the MSE in this instance [267 / (20 – 2 – 1)] = 15.706
