It is important for you to able to analyze a correlational study and explain how it differs from a cause-and-effect outcome.
Include Part A and Part B in your PowerPoint Presentation.
Using the same scenario you used in Part I (see your week 3 paper) and II (see your week 4 paper) of this project,
you will now present your findings to your company or clinic staff, including CEOs (think about your audience).
Part A:
Provide a response to the following prompts:
Imagine your research team has been tasked with finding the correlation of 2 variables from your scenario. The data below includes 4 research participants’ data for variable 1 (high scores mean better of variable 1 ) and data for variable 2 (high scores mean more of the variable). The scores are as follows:
Person Variable 1 Variable 2
1 1 10
2 1 8
3 2 4
4 4 -2
Describe the process your research team would go through by completing the following:
1. Create a scatter diagram of the scores.
2. Describe in words the general pattern of correlation, if any.
3. Figure the correlation coefficient.
4. Explain the logic of what you have done, writing as if you are speaking to someone who has never heard of correlation (but who does understand the mean, standard deviation, Z scores, and hypothesis testing).
correlation (but who does understand the mean, standard deviation, Z scores, and hypothesis testing).
5. Provide 3 logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation based on the variables involved. Explain your answer. (Provide 3 logically possible directions using your scenario)
Part B:
Assume your research is complete and you have written your research article. Now it’s time to make a public presentation for your company/clinic.
Consider your audience and the language you will need to use to make this presentation clear for all participants.
Create a 10- to 12-slide Microsoft PowerPoint presentation (the title slide and reference slide do not count in this number) using the information you gathered and submitted in Parts I (see your week 3 paper) and II (see your week 4 paper).
Include the following in your PowerPoint Presentation:
• Describe the problem and provide some brief background information about the situation.
• Explain the alternative hypothesis.
• Describe your sample and your sampling method.
• Explain the 4 steps of the research process you followed.
• Define the critical value and the test statistic your analysis provided.
• Copy and paste your t-Test: Two-Sample Assuming Equal Variance table into your PowerPoint Presentation.
• Include your scatterplot, correlation coefficient, and correlation findings from Part A.
• Provide 3 logically possible directions of causality, indicating for each direction whether it is a reasonable explanation for the correlation based on the variables involved. Explain your answer. (Provide 3 logically possible directions using your scenario from Part A.
• Provide the main finding of the study. What did you prove or fail to prove?
• Provide recommendations based on your findings.
Each slide must have 4 to 5 bullet points with 4 to 5 words for each point plus speaker notes. The bulk of your explanation will go in the speaker notes. This is where you will write and put what you would say when giving this presentation to your audience. This is an academic presentation: therefore, keep the bells and whistles to a minimum and make this a clean, professional-looking presentation. It is a visual presentation, so tasteful and related images are appropriate.
Include a Title slide and Reference slide in your PowerPoint Presentation.
Format your citations in your PowerPoint Presentation according to APA guidelines.
Also, if photos are used, they need to be referenced according to APA guidelines.
Submit your assignment as a Microsoft PowerPoint Presentation.
