Camera angle can make a difference in advertising; it can even affect the viewer’s evaluation of a product. A research article reported a main effect for camera angle (F_2,29 = 14.48, p<0.001) based on an analysis of variance. The average score was 4.51 for eye-level camera angle, 5.49 for a low-angle looking up, and 3.61 for a high angle looking down. Higher scores represent more positive evaluations of the product (a personal computer). Are there significant differences among these three camera angles? If so, which angle appears to be best?
