quantitative Reasoning and Analysis (statistics for health education ) week 8 A
Assignment 1: Testing for Correlation and Bivariate Regression
You had the chance earlier in the week to practice with the correlation and simple linear regression and obtain peer feedback. Hopefully you are excited about the potential these tests hold; equally important is that you recognize some of their weaknesses. Now, it is once again time to put all of that good brainstorming to use and answer a social research question with the correlation and simple linear regression. As you begin the Assignment, be sure and pay close attention to the assumptions of the test. Specifically, make sure that your variables are metric level variables that can easily be interpreted in these tests.
For this Assignment, you will examine correlation and bivariate regression testing.
To prepare for this Assignment:
Review this week’s Learning Resources and media program related to regression and correlation.
Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week.
Based on the dataset you chose, construct a research question that can be answered with a Pearson correlation and bivariate regression.
Once you perform your correlation and bivariate regression analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.
For this Assignment:
Write a 2- to 3-paragraph analysis of your correlation and bivariate regression results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be.
Use proper APA format, citations, and referencing for your analysis, research question, and display of output.
By Day 7
Submit your Assignment 1: Testing for Correlation and Bivariate Regression.
Assignment 2: Correlation and Bivariate Regression in Practice
For this Assignment, you will continue your practice as a critical consumer of research. You will critically evaluate a scholarly article related to correlation and bivariate regression.
To prepare for this Assignment:
Use the Course Guide and Assignment Help found in this week’s Learning Resources and search for a quantitative article related to correlation and bivariate regression.
For this Assignment:
Write a 2- to 3-page critique of the article you found. In your critique, include responses to the following:
Why did the authors use correlation or bivariate regression?
Do you think it’s the most appropriate choice? Why or why not?
Did the authors display the data?
Does the results table stand-alone (i.e., are you able to interpret the study from it?) Why or why not?
Use proper APA format, citations, and referencing.
By Day 7
Submit your Assignment 2: Correlation and Bivariate Regression Practice.
Week 8: Correlation and Bivariate Regression Correlation tests are some of the most widely used tests; unfortunately, they are also some of the most misinterpreted tests. The term correlation is frequently used in a colloquial sense, but has a very specific definition within the context of statistics. As a critical consumer of research, after this week you will be able to properly interpret the strengths and weaknesses of this specific test. Perhaps the most exciting part of this week’s activities is the introduction to ordinary least squares regression. This form of linear regression is frequently referred to as the “workhorse” of the social sciences, and for good reason. It is one of the most widely used statistical tests. In this week, you will examine correlation and bivariate regression. In your examination you will construct research questions, evaluate research design, and analyze results related to correlation and bivariate regression. Learning Objectives Students will: Construct research questions Evaluate research design through research questions Analyze correlation and bivariate regression Analyze measures for correlation and bivariate regression Analyze significance of correlation and bivariate regression Analyze results for correlation and bivariate regression testing Analyze assumptions of correlation and bivariate regression Analyze implications for social change Evaluate research related to correlation and bivariate regression Learning Resources Required Readings Frankfort-Nachmias, C., & Leon-Guerrero, A.
