A researcher is interested in the effects of coffee consumption (0, 1, or 2 cups) and TV
viewing (0 or 30 mins) on how sociable subjects feel. University students participated in this
study, with 20 students randomly assigned to each condition. After watching TV for either 0 or
30 mins, while drinking either 0, 1 or 2 cups of coffee, subjects were asked to rate how sociable
they felt on a scale of 1 to 15, where 15 represented the most sociability.
Place the data into the cells of the matrix and determine the row and column means (a handdrawn matrix is fine).
