It is important for you to able to analyze a correlational study and explain how

It is important for you to able to analyze a correlational study and explain how it differs from a cause-and-effect outcome.
Using the same scenario you used in Part I and II of this project, you will now present your findings to your company or clinic staff, including CEOs (think about your audience). **Please ensure you scroll ALL the way down to view ALL of the instructions for this final project. You are COMBINING all your parts into ONE final presentation that includes a new section on correlation too! You are submitting ONE final PowerPoint presentation that includes the information from Part A in addition to the information in Part B. Your final presentation should include your work from Parts 1, 2 and Part A below, on correlation.
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:
Create a scatter diagram of the scores.
Describe in words the general pattern of correlation, if any.
Figure the correlation coefficient.
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).
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.
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 (cover slides and references do not count in this number) using the information you gathered and submitted in Parts I and II and including your information you obtained from Part A above.
Include the following in your presentation:
Describe the problem and provide some brief background information about the situation.
Explain the research 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.
Include your scatterplot and correlation findings from Part A, including your answers to all the questions 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. You should use a professional design template. It is a visual presentation, so tasteful and related images are expected and appropriate.
Format any citations in your presentation according to APA 7th edition guidelines. Do not use bullet points for your references; use proper hanging indents and spacing. You may use as many reference slides as you need since they are not part of the content total. Also, if photos are used, they need to be referenced according to APA guidelines.

QUESTION 1 A ratio level variable has a Mean of 87, a Median of 80, Skew = -0.43

QUESTION 1
A ratio level variable has a Mean of 87, a Median of 80, Skew = -0.43, Kurtosis = +0.64, Shapiro-Wilk = 0.07: is the variable normally distributed Y/N? Why? Be specific about each statistic. Slides 45, 117
QUESTION 2
If Levene’s Sig. = .038, what type of t Test is it, be specific? Why? If the t Test Equal Variances Assumed P actual = .021 and the Equal Variances Not Assumed P actual. = .028, which one do you use? Is there an association at the 95% Confidence Level? Why? Slides 79, 88, 122, 123, 125, 126
QUESTION 3
A researcher gave a group a test. The mean was 92. The researcher compared this to the mean of the population which is 85. P actual was .026. What type of t test is this, be specific? Is there an association at the 95% Confidence level? Why? What is the difference in the means, amount and direction? Slides 79, 88, 122, 133, 134

QUESTION 4
A researcher wanted to determine if High School GPA (HSGPA) measured as a number to two decimal places is a good predictor of First Year College GPA (FYGPA) measured in the same way. Pearson Correlation was .55, P actual. = .04. Is there an association at the 95% Confidence Level? Why? If yes, strength? Percent causation? Interpret? Slides 79, 146, 147, 148

QUESTION 5
A researcher wanted to develop a predictive model using regression analysis for the scenario in question 4. Pearson R = .620, Constant = 2.0, Slope = .4. What is Pearson R strength? Percent causation? State the regression equation? Predict FYGPA for HSGPA = 2.5? Slides 153, 154, 155

QUESTION 6
When do you use Analysis of Variance (ANOVA)? What are the types? How do you decide which one to use, be specific including the relevant statistic and its value? Why do you use the Bonferroni Post Hoc Test? How does it help? What statistic do you use to determine strength? Interpret .684? What is the percentage causation? Slides 136 to 143
