webassign.net what Is The F Value, Explain Researcher Records The Following Data For Eacho Topic Six Homework 17, -/11 points PriviteraStats21 3.?.023. My Notes Ask Your + A study investigated the effects of physical fatigue on the performance of professional tennis players. Researchers measured the number of unforced errors committed by a random sample of 12 professional tennis players during the first three sets of a match. They hypothesized that increased fatigue would be associated with a greater number of errors. The following is an F-table for this hypothetical study using the one-way within-subjects ANOVA Source of Variation SS Between groups Between persons Within groups (error 44 Total df MSF 15 (a) Complete the F-table. Source o Variation Between groups Between persons Within groups (error) Total df MS Fobt 15 Make a decision to retain or reject the null hypothesis. (Assume alpha equal to 0.05.) Retain the null hypothesis. Reject the null hypothesis. (b) Estimate effect size using partial omega-squared: p2. (Round your answer to two decimal places.) You may need to use the appropriate table in Appendix B to answer this question. Additional MaterialsExplanation / Answer

F(2,22) critical at 0.05 =3.44
Calculated F=7.5 > critical F value 3.44.
Reject the null hypothesis.
Effect size = 30/(30+44) = 0.4054
=0.41 ( two decimals)
