ANOVA Statistics Significant Testing

11. A researcher is interested in studying whether music helps or hinders learning. He selects a random sample of 21 participants and has all participants study material of equal difficulty under three listening conditions: listening to silence, listening to a conversation, and listening to music. The participants complete these tasks in a randomized order. The groups means are as follows: Silence: M = 80.2; Conversation: M = 83.4; Music: M = 85.2 a. What test would you use to analyze this data? Be Specific (1 pt) b. The researcher calculates the following F-value: F = 4.750. Calculate the appropriate degrees of freedom and use the F-table to find a critical value. (2 pts) F(, ) = 4.750, Forit = c. Is this a significant finding? (1 pt) d. What kind of post hoc test should be used? (1 pt) e. Post hoc tests reveal significant differences between all three conditions. What listening conditions seem to be the best, based on this study? (1 pt)
