Here we have data that represent the results of a study comparing different viewing distances for a 42 inch high definition television. Four viewing distances were evaluated, 9 feet, 12 feet, 15 feet and 18 feet. Each participant watched a 30 minute television program from one of the distances and then rated the viewing distance on a scale from 1 (Very Bad, definitely need to move closer or father away) to 7 (excellent, perfect viewing distance). The following day, the participants returned and watched another program from a different distance. This process continued until all five participants had experienced and rated all four distances.
