Identify the Independent Variable: 2. What are the levels of the Independent Variable? ( ,& 3. What is the Dependent Variable: 4. Fill out all the missing items in the table. 5. What is the problem? 6. Formulate the statistical null and alternate hypotheses. 7. Formulate the research hypotheses (null and alternate) 8. What is the level of significance? 9. Determine SSw, SSB, and SST (use formulas on the board) SSw = EXi' + EX2' + EX3' - [(EX1)'i + (EX2)?2 + [(EX3)?3] . SSB = [(EX1)'i + (EX2)?2 + [(EX3)?3] -(EX1 + EX2 + EX3)/N SST = EX,'+ EX2 + EX3 - (EXi + EX2 + EX3)/N 10. Fill out the Summary Table for One-Way ANOVA Sources of Variation SS DF MS FOBT FORIT - Between . Within - Total **Transfer computed sums of squares * *compute DFBETWEEN, DFWITHIN, and DF TOTAL DFBETWEEN = K - 1 DF WITHIN = N - K DFTOTAL = N - 1 **compute MSBETWEEN and MSWITHIN (MS = SS/DF) **compute FOBT = MSBETWEEN / MSWITHIN **test your null hypothesis 11. Compute Effect Size = SSBETWEEN / SSTOTAL 12. Write results in APA format 13. If results are SIGNIFICANT, proceed to the POST-HOC test (Scheffe Test) The Scheffe Test uses the following formula: F = (M1 - M2) 2 MSw (N1 + N2 )/N1 " N2 14.
