# Probability - Independent - Related-Samples t-test

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

Bring to mind a real-world situation or problem that could be addressed using an independent- or related-samples t test. However, the real-world situation or problem selected to address, the independent and dependent variables you would study, an explanation of whether an independent-samples or related-samples t test is most appropriate, 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, and your hypothetical results using correct APA format.

For this situation or problem:

Clearly identify the independent and dependent variables you would study.

Determine whether an independent-samples or related-samples t test is most appropriate and why.

Generate the statistical null and alternative hypotheses.

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

Using realistic numbers for values of degrees of freedom, sample size, and t-statistic, report hypothetical results in a few sentences using correct APA format.

## Real World problem: Identify variables, samples, t test, null and alternative hypothesis

Bring to mind a real-world situation or problem that could be addressed using an independent- or related-samples t test. do not need to use the SPSS to complete.

For this situation or problem:

Clearly identify the independent and dependent variables you would study.

Determine whether an independent-samples or related-samples t test is most appropriate and why.

Generate the statistical null and alternative hypotheses.

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

Using realistic numbers for values of degrees of freedom, sample size, and t statistic, report hypothetical results in a few sentences.

So with this in mind take the real-world situation or problem you selected to address, the independent and dependent variables you would study, an explanation of whether an independent-samples or related-samples t test is most appropriate, 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, and your hypothetical results.
