IMPORTANT NOTE REGARDING WORD LIMIT REQUIREMENTS:
Please note that each and every assignment has its own word limit.
The purpose of this assignment is to apply your understanding of simple and multiple linear regression.
For this assignment, use the “Example Dataset” to complete a simple linear regression using SPSS. Select one dependent variable, one primary independent variable, and one potential confounding variable. You will need to recode string variables into numeric variables to use them in the regression analysis. Prepare a Word document that includes all SPSS outputs.
Based on the results, create a second Word document and answer the following questions in 500-750 words.
State your research question and hypotheses.
Run the regression again without the potential confounding variable and discuss the impact on the coefficient of the primary independent variable. Did it change? If so, to what extent did it change? Based on this, do you think the added variable confounds the association between the independent and dependent variables?
Export both regression output tables as part of the Word document containing the SPSS outputs.
Provide your regression equation based on the results of the full regression model.
Interpret the results by (a) stating the reason the study or test was done; (b) presenting the main results, including coefficients on the main independent variable and significance levels; (c) explaining what the results mean; and (d) making suggestions for future research.
Submit both Word documents to the instructor.

MUST have 500 to 750 WORDS and at least 5 citations with the page numbers and 5 references in APA format.(The List of References should not be older than 2016 and should not be included in the word count.)
Be sure to support your postings and responses with specific references to the Learning Resources.
It is important that you cover all the topics identified in the assignment. Covering the topic does not mean mentioning the topic BUT presenting an explanation from the context of ethics and the readings for this class
I am a stickler for good organization in everything. I do not want to have to dig for your answers. For instance, if an assignment asks you to provide three examples of something, I suggest that you number them 1-3 so I can find them easily. I also expect that when you submit something as a narrative, you pay attention to how you organize your thoughts: use paragraphs with a topic sentence and supporting sentences; and change paragraphs whenever you introduce a new idea. Also, if there are multiple parts to an assignment, use sub-heads within the paper to organize them.
To get maximum points you need to follow the requirements listed for this assignments 1) look at the word/page limits 2) review and follow APA rules 3) create subheadings to identify the key sections you are presenting and 4) Free from typographical and sentence construction errors.
REMEMBER IN APA FORMAT JOURNAL TITLES AND VOLUME NUMBERS ARE ITALICIZED.
