This data from ‘halo1.dat’ is taken from the Journal of Personality and Social Psychology (1974): A study was designed to determine if a persons essay quality or attractiveness played a role in the grading of essays. Column 1 in the data is essay quality (rated good=1,poor=2), the second column is student attractiveness (1=attractive, 2=control, 3=unattractive). And the third column is the response (essay score). Construct an interaction plot and the full anova table (row for treatment as well as each factor). The ‘.dat’ file is a tab delimited text file. 2.

The results are included in column 2 and are a measurement of the post-test procedural knowledge score. Construct an anova table to determine if the method of instruction had an effect on the procedural knowledge score.
