Question: A researcher recorded the calories burned by subjects during a 10-minute treadmill exercise. All participants had televisions located in front of them while exercising. In one group, the television played music videos. In a second group, the television played a news channel. In a third group, the television was turned off. Based on the following description in APA format, state the value of k, n, and N, and interpret the effect size as small, medium, or large.
A one-way analysis of variance reached significance, F(2, 57) = 4.26, p < .05 (co 2 = .11 ), with participants watching the music video burning significantly more calories compared to participants watching the news channel or those watching no television (LSD, p < .05). Otherwise, no significant differences were evident (p > .05).
