Week 8 discussion
Correlation and Bivariate Regression
Similar to the previous week’s Discussion, this Discussion
assists in solidifying your understanding of statistical testing by engaging in
some data analysis. This week you will once again work with a real, secondary
dataset to construct a research question, perform a correlation and bivariate
regression model, and interpret the results.
Whether in a scholarly or practitioner setting, good
research and data analysis should have the benefit of peer feedback. For this
Discussion, you will post your response to the hypothesis test, along with the
results. Be sure and remember that the goal is to obtain constructive feedback
to improve the research and its interpretation, so please view this as an
opportunity to learn from one another.
To prepare for this Discussion:
Review this week’s Learning Resources and media program
related to regression and correlation.
Review Magnusson’s web blog found in the Learning Resources
to further your visualization and understanding of correlations between two
variables.
Construct a research question using the General Social
Survey dataset, which can be answered by a Pearson correlation and bivariate
regression.
By Day 3
Use SPSS to answer the research question. Post your response
to the following:
What is your research question?
What is the null hypothesis for your question?
What research design would align with this question?
What dependent variable was used and how is it measured?
What independent variable is used and how is it measured?
If you found significance, what is the strength of the
effect?
Explain your results for a lay audience; explain the answer
to your research question.
Be sure to support your Main Post and Response Post with
reference to the week’s Learning Resources and other scholarly evidence in APA
Style.
By Day 5
Respond to at least one of your colleagues’ posts and
comment on the following:
Do you think the variables are appropriately used? Why or
why not?
Does the analysis answer the research question? Be sure and
provide constructive and helpful comments for possible improvement.
If there was a significant effect, comment on the strength
and its meaningfulness.
As a lay reader, were you able to understand the results and
their implications? Why or why not?
