Design a repeated measures experiment that investigates the effect of report presentation style on the grade received for the report. Use two levels of the independent variable: a “professional style” presentation (high quality paper, consistent use of margins and fonts, carefully constructed tables and charts) and a “nonprofessional style” (average-quality paper, frequent changes in the margins and fonts, tables and charts lacking proper labels). Discuss the necessity for using counterbalancing. Create a table illustrating the experimental design.
