5. Extra credit: You come across a research study that reports the following incomplete F table for a one-way within-subjects ANOVA at a .05 level of significance. Hint: All cells in the table cannot be completed, but enough cells can be completed to identify the F statistic. Sources of Variation SS df MS F Between Groups 50 2 25.0 4.00 Between Persons 140 12 11.67 Within Groups (Error) 150 24 6.25 Total 340 38 a. What was the sample size for this test? (3 points) b. Was a repeated-measures or a matched-pairs design used in this study? (3 points) c. Compute eta-squared for the effect reported. (5 points) d. Write the results in an APA style sentence. (5 points)

Use the following table to complete the ANOVA table below for a within subjects one-way ANOVA with 6 participants who were measured on the same variable (x) following 4 different treatments: ANOVA Table Source of Variation Sum of Squares Degrees of Freedom Mean Square F Between Groups SSbg dfbg MSbg Fbg Between Persons SSbp dfbp MSbp Fbp Within Groups SSwg dfwg MSwg Fwg Total SStotal dftotal Do we retain or reject the null hypothesis? Substantively interpret this decision. If significant, calculate the effect size and interpret. What would be our next step if we wanted to determine which pairs of means were statistically significantly different?

Partially completed ANOVA table for a completely randomized design is shown: Source Treatments Errors Total SS MS 30.899 121.78 Complete the ANOVA table. b) How many treatments are involved in the experiment? What is the sample size? c) Write the hypotheses to test if the treatment means are different. d) Do the data provide sufficient evidence to indicate a difference among the population means? Consider α = 0.05.
