Question:

Bring to mind a real-world situation or problem that could be addressed using a analysis of variance (ANOVA). You will not need SPSS to complete this Discussion question.

? For this situation or problem:

o Clearly identify the independent and dependent variables in this article , including the number of levels of the independent variable.

o Generate the statistical null and alternative hypotheses.

o Describe what information the effect size would tell you that the probability value would not tell you.

o Explain what additional information confidence intervals around means (or around mean differences) would give your reader.

o Explain when would you need to report a post hoc test and why.

o Using realistic numbers for values of degrees of freedom, sample size, F-ratio, and confidence interval(s) (if appropriate), and post hoc results (if appropriate), report hypothetical results in a few sentences using correct APA format.

With these thoughts in mind:

Post by Day 4 the article you selected to address, the independent and dependent variables you would study and the number of levels of the independent variable, the statistical null and alternative hypotheses, a description of what information the effect size would tell you that the probability value would not tell you, explain what additional information confidence intervals around means (or around mean differences) would give your reader; explain when would you need to report a post hoc test and why; and using realistic numbers for values of degrees of freedom, sample size, F -ratio, confidence interval (s) (if appropriate), and post hoc results (if appropriate), report hypothetical results in a few sentences using correct APA format.
