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.

How to do the assumptions part of the week 8 assignment?

Hello everyone,

Part of our assignments includes discussing assumptions. I have noticed that we might need help in this area. To help in the week 8 assignment, I posted a week 8 assignment outline with links for the correlation and regression tests we will be doing this week. In these links, there are at least 4 assumptions described. Since assumptions 4 and greater are beyond this course we will only address assumptions 1, 2, and 3 for the assignment. So for both tests, you can examine your variables to see that they are continuous, ensure that a scatterplot is essentially linear with no significant outliers (we addressed scatterplots in the first assignment). If the plot is not linear or with significant outliers (very far from the line of best fit) then change the variables. (A tip, you can use the same variables for the two tests if you would like to.) For the assignment, you just have to describe these three characteristics in the subsection under assumptions.

Here is a video on correlation and scatter plots to help you with this week’s assignment.

You will also find attached an example to follow for the week 8 assignment.

Here is the layout for the assignment

First

Please add an introduction to your paper before you begin it with tables. This will help the organization of your content.

Second

Identify the dataset

Identify the variables

Third

State the research question

Is there a statistically significant relationship between…

Fourth

Please evaluate if the assumptions 1,2 and 3 of the tests are met.

Here is a list of them

Use this to site to help you run and interpret the Pearson’s correlation coefficient.

There are guidelines to interpreting Pearson’s correlation coefficient:

	Coefficient, r
Strength of Association	Positive	Negative
Small	.1 to .3	-0.1 to -0.3
Medium	.3 to .5	-0.3 to -0.5
Large	.5 to 1.0	-0.5 to -1.0

Provide an explanation of what the implications of social change might be.

Use proper APA format, citations, and referencing for your analysis, research questions, and output.
