(A) -(E)Draw a Graph of the Cell Means for Each

Short Answer

(a) -(e)Draw a graph of the cell means for each of the tables above. Let the horizontal axis represent the column variable. In each case, see if you can arrive at correct conclusions concerning the presence (or absence) of row, column, and interaction effects from the graph alone. Bear in mind that the tables of Problem 1 are highly artificial; they are population values and do not reflect the effects of the sampling variation that would be encountered in practice.
