Chi-Square

To gain experience with applying hypothesis testing to a pair of qualitative (categorical) variables, you will be using data from the American National Election Studies (ANES) 2020 Social Media Study. The study was conducted by Stanford University and the University of Michigan. You will be using the March 8, 2021 version of the dataset. The dataset contains answers to survey questions from over 5,000 respondents. The data provided for you is a selection of variables from the actual dataset, with some minor modifications for usability in this course.

American National Election Studies. (n.d.). 2020 social media study. https://electionstudies.org/data-center/2020-social-media-study/

The variables in the dataset can be separated into two main groups: profile variables (that describe the survey respondent) and news/social media usage variables. You will select one profile variable and one news/social media usage variable to analyze using chi-square analysis. You will be using the data to determine whether there is a significant association between your two selected variables or not. There are many variables to choose from, so you must select a pair that has not been used by one of your classmates.

Carry out the following steps. Watch the Unit 8 Discussion video in the LiveBinder for a demonstration.

  1. Download the spreadsheet containing the Social Media Study data.
  2. Download the document that defines the variables and codes used. You will need this to be able to determine which are profile variables, which are news/social media usage variables, and to interpret the levels of each variable. For example, the profile variable “phoneservice” has levels 1, 2, 3, 4, and 5. You need this document to find out what each code (number) means.
  3. In the Virtual Office, your instructor has posted a “Unit 8 Discussion Variable Selection Sheet.” You will use this spreadsheet to select a pair of variables to analyze in your discussion post. You will select a pair that consists of one qualitative variable from the list of news/social media usage variables and one qualitative profile variable from the list of profile variables. Enter your name in the spreadsheet beside the pair you wish to analyze. If a pair already has a name beside it, you must select a different pair.
  4. State your profile variable name, the survey question it represents (if one is given), and define the levels of the variable. State your news/social media usage variable name, the survey question it represents, and define the levels of the variable.
  5. What influenced your decision to choose those two variables?
  6. What is your research question? The question should be in the format of “Is there an association between ___ and ___?”
  7. What is the Ho and Ha?
  8. Use the Excel chi square worksheet to calculate your test statistic and p-value and generate an appropriate graphical display. (Note: This worksheet can only be used if you have no more than 8 rows and 8 columns.)
  9. Calculate the test statistic and p-value.
  10. Compare your p-value to alpha (assume alpha = 0.05) and state your decision.
  11. What is your conclusion in the context of your research question?
  12. Make a segmented bar chart with your variables using Excel, insert the image into your post using the snipping tool, and discuss the association or lack of association that you see from your graph in the context of your research question. Be specific. Remember that the graph should illustrate the decision you made regarding the hypothesis test.

Use the following information to ensure successful completion of the assignment:

  • Refer to your Topic 2 submission of “Learning and Hopfield Networks.”
  • This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.
  • Doctoral learners are required to use APA style for their writing assignments. The APA Style Guide is located in the Student Success Center.
  • Refer to the Publication Manual of the American Psychological Association for specific guidelines related to doctoral level writing. The Manual contains essential information on manuscript structure and content, clear and concise writing, and academic grammar and usage.
  • This assignment requires that at least two additional scholarly research sources related to this topic, and at least one in-text citation from each source be included.
  • You are required to submit this assignment to LopesWrite. A link to the LopesWrite technical support articles is located in Class Resources if you need assistance.

Directions:

Part 1

Present a revised version (1,500-1,800 words total) of the paper “Learning and Hopfield Networks” that makes improvements in the caliber of the writing and incorporates instructor feedback regarding content and writing. Include the following in your submission:

  1. A reflection (250-300 words) that provides a bulleted list of the changes you made to the paper and discusses your revision process including how you incorporated your instructor’s feedback into the revised version. Similar to an abstract, this section will receive its own page following the title page and preceding the introduction to the paper.
  2. The revised paper that incorporates instructor feedback; clarifies the thesis statement and solidifies supporting arguments; edits for grammar, spelling, and punctuation; adjusts word choice to display professional and scholarly language; and adjusts sentence structure for improved readability.

Part 2

Write an additional 1,250-1,500 words in which you explore the interrelation of creativity, intelligence, memory, and learning. This section should flow naturally from the revised paper. So, you may also need to revise your introduction and thesis statement to allow the ideas to connect. Do the following:

  1. Analyze the interrelation of creativity, intelligence, memory, and learning.
  2. Discuss how your view of Hopfield networks influences your analysis.
  3. Describe how the interrelation of creativity, intelligence, memory, and learning can be exploited to enhance student learning outcomes.

Since the tools of correlation and regression are only appropriate for quantitative data, you will select a pair of quantitative variables from this dataset to analyze. Complete the following steps to select your variables and conduct the analysis. Watch the Unit 7 Discussion video in the LiveBinder for a demonstration of how to do these things in Excel.

a.   Use the Unit 7 Variable Selection Spreadsheet that your instructor has posted in the Virtual Office to determine which two quantitative variables you will use in your analysis. Select a pair of variables that a classmate has not previously selected by putting your name in the first column beside the pair you choose; unless all the variable pairs have already been claimed, then you will put your name in the second column beside the pair you select. Name the pair of variables that were selected for you and describe them (based on what you read in Step 1).

b.  Download the dataset, copy the data for these two variables and paste it into a new sheet, which you will attach to your post at the end.

c.   Which variable is your independent variable? Which one is your dependent variable?

d.  What is your research question? The question should be in the format of “Is there a significant correlation between ___ and ___?”

e.   Use the Unit 7 Discussion video “Correlation and Regression” in the Unit 7 LiveBinder to help you create a scatterplot (include axis labels) and give the correlation coefficient, r. Discuss any relationship you see from the scatterplot and r value: Does there appear to be a linear or nonlinear relationship? Is the relationship positive or negative? Is the linear relationship weak, moderate, or strong?

f.    Next, you will conduct an appropriate hypothesis test. What is the name of the test you will run? What are the Ho and Ha?

g.  The discussion video also demonstrated how to conduct the regression analysis in Excel. Insert your Excel regression output in your response using the snipping tool and Insert Image.

h.  What is your t-test statistic? What is your p-value? Assuming alpha = .05, what is your decision regarding rejection?

i.    What is your conclusion in context?

j.    Give the regression model equation, pick a reasonable hypothetical value for your independent variable, and use the equation to get a prediction for the value of your dependent variable. Based on your previous analysis, do you trust this prediction? Explain.
