A 2 × 2 factorial experiment was designed to test the impact on mail survey response rate resulting from variations in paper trim size and number of printed pages in the questionnaire. ANOVA findings suggest 8½ × 11″ paper trim size produces a better response rate than an 8½ × 14″ paper trim size. Use of a one-sheet (front and back) versus a two-sheet (front only) questionnaire did not cause a significant difference in response rate; a hypothesized interaction effect was not found to be statistically significant.
