A university statisties department is conducting a series of randomized comparative experiments to compare teaching
methods. Response variables include students' final exam scores and a measure of their attitude toward statisties.
One study compares two levels of technology for large group lectures: standard (overhead projectors and chall) and
multimedia. The experimental units in the study are the lecture sections in a basic statisties course, taught by four
different instructors as shown in the table below.
