Plotting interactions in SPSS
The syntax below will plot two lines (for the factor with two levels: social=1 and social=2) with each line representing the means of metaphor=1 and metaphor=2. 95% confidence intervals can be added to each of the four means. The data is entered as three columns of raw data corresponding to: metaphor1 (continuous values for metaphor=1), metaphor2 (continuous values for metaphor=2) and social (1 or 2).
