Use the descriptive statistics below to calculate your df, then complete the ANOVA table Table 11.6.1- Descriptive Statistics for each IV level and the Total N: Mean: SD: Median: No Intervention 10 42.70 8.18 43.00 Minimal Intervention 10 44.40 5.87 43.00 Super Intervention 10 51.10 4.93 50.50 Total 30 46.07 7.25 48.00 Table 11.6.4- ANOVA Summary Table with SS only Source SS df MS F Between 394.60 Within 1131.40 Tota 1525.87One-way ANOVA - Example 1 (Types of Music) An experimenter is interested in the effect of music on memory for words. The data are shown below. Each score represents the number of words recalled. Analyze the data using the appropriate statistical tests. Step 1. State your hypotheses. a. Research hypotheses HA: Ho: b. Statistical hypotheses HA: Ho: Step 2. Set the significance level > a = .05 Determine Ferit. dfbetween = df within = Forit = dfbetween = k - 1 dfwithin = Ntot - k dflot = Not - 1 dflot = dfbetween + dfwithin Step 3. Select and compute the appropriate statistic and then complete the source table.

Make a decision. Determine whether the value of the test statistic is in the critical region. Draw a picture. Label Ferit and Fobt. Is Fobt in the critical region? Ferit = Fobt = Step 5. Report the statistical results. Step 6. Write a conclusion. Step 7. Compute eta-squared and write a conclusion. 12 = SS between SStotDescription Link to Answers Note: I chose to round my Total mean to 5, for ease of calcualtion, instead of using the exact mean of 4.98. If you chose to use the exact mean of 4.98, your SS between would be 88.29, SS total would be 105.04, and your final F-value would be 28.99. One-Way ANOVA Worksheet 1 (1).pdf
