A study was conducted in which the critical threshold temperature eliciting heat pain and the response latency to the first heat pain sensation were compared. Subjects were healthy adults between the ages of 23 and 54 years. Among the data collected were the following latencies (seconds) to the first pain response induced by radiant heat stimulation at three different skin temperatures: Subject 25C 30C 35C 1 6.4 4.5 3.6 8.1 5.7 6.3 9.4 6.8 3.2 6.75 4.6 3.9 10 6.2 6.2 4.5 4.2 3.4 mun-hours: Which of the following is an appropriate research question for an analysis using ANOVA? a) At what temperature is the latency shortest? b) Does the latency reduce over time? C) Is latency a useful predictor of temperature? d) Is the average latency the same among the different temperatures? e) ls temperature a useful predictor of latency? f) None of these. Which of the following is the correct type of design / setup? a) Completely Randomized Design (one-way ANOVA) with the Subject factor type set to Fixed. b) Completely Randomized Design (one-way ANOVA) with an interaction term added to the model. c) Completely Randomized Design (one-way ANOVA) with the Temperature factor type set to Random. d) Randomized Block Design (two-way ANOVA) with the Subject factor type set to Fixed. e) Randomized Block Design (two-way ANOVA) with an interaction term added to the model. f) Randomized Block Design (two-way ANOVA) with the Temperature factor type set to Random. g) Repeated Measures Design (two-way ANOVA) with the Subject factor type set to Random. h) Repeated Measures Design (two-way ANOVA) with an interaction term added to the model. i) Repeated Measures Design (two-way ANOVA) with the Temperature factor type set to Random. Suppose that the analysis yielded the following (partial) ANOVA table: Source DF SS MS F P Subject 15.2157 3.0431 2.78 0.079 Temp 30.3436 15.1718 13.87 0.001 Error 10.9347 1.0935 Total 56.494 Suppose that the analysis yielded the following (partial) ANOVA table: Source DF SS MS F P Subject 15.2157 3.0431 2.78 0.079 Temp 30.3436 15.1718 13.87 0.001 Error 10.9347 1.0935 Total 56.494 How many error degrees of freedom are there for this ANOVA design? Is the factor of interest significant at 5%
