Question

The results of a two-factor, independent-measures, equal n experiment are summarized in the following matrix. The numerical value in each cell is the mean score obtained from the sample in that treatment condition B B2 А M=4 M-2 M- Az M = 6 M-8 ME M M Compute the overall means for the scores in A, the scores in Az, the scores in B, and the scores in B2. Enter each of the means to the right of the appropriate row or below the appropriate column in the matrix. Make a graph of the results of the experiment. Use the blue points (circle symbol) to plot the means for level 1 of factor A (A1). Use the orange points (square symbol) to plot the means for level 2 of factor A (A2). (Note: Line segments will automatically connect your points.) Treatment Mean 10 factor A. Level 1 9 8 factor A, level 2 7 6 5 4 3 2 1 Level 1 Level 2 factor Clear All Use the overall means and your graph to decide whether there appears to be a main effect for factor A, a main effect for factor B, and an interaction

Answer 1

solution: page-1 » from the given information Bi B2 Mean A, 4 2 4+2 2 6 -3 3 A₂ 6 6+8 8 14 =7 2 4+6=10 10 2 278 2 = 2 5 5 10 Az 8 6 4 3 Ai 2 a Bi В, - By using over all means and graph to decide whether there appers to be main effect factor A main effect of factor 'B' and an intesaction, main effect for factor 'A' - Yes main effect for factor 'B'. NO Interaction = NO. X
