Assignment: Experimental Design BOOLEN METHOD
Select a peer-reviewed, experimental research study that exemplifies a two-group design and a factorial design (use keywords method, results, and discussion in your Boolean search). These studies can be found using tools such as the GCU Library and Google Scholar.
Write a 500-750-word paper in which you:
- Compare the two research designs.
- Identify the independent variable(s), dependent variable, and any possible extraneous variable.
- Identify main effects and interactions for the factorial design.
- Explain if the study has a random sample and/or random assignment. Were there other limitations that were noticed?
Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required. Assignment: Experimental Design BOOLEN METHOD
Assignment: Experimental Design BOOLEN METHOD
In this module, the four approaches to quantitative research are described and examples are provided.
- List and explain the four approaches to quantitative research.
- Provide an example of each method.
- Describe how to identify the appropriate approach for a particular research problem.
There are four main types of quantitative research designs: descriptive, correlational, quasi-experimental and experimental. The differences between the four types primarily relates to the degree the researcher designs for control of the variables in the experiment. Following is a brief description of each type of quantitative research design, as well as chart comparing and contrasting the approaches.
A Descriptive Design seeks to describe the current status of a variable or phenomenon. The researcher does not begin with a hypothesis, but typically develops one after the data is collected. Data collection is mostly observational in nature.
A Correlational Design explores the relationship between variables using statistical analyses. However, it does not look for cause and effect and therefore, is also mostly observational in terms of data collection.
A Quasi-Experimental Design (often referred to as Causal-Comparative) seeks to establish a cause-effect relationship between two or more variables. The researcher does not assign groups and does not manipulate the independent variable. Control groups are identified and exposed to the variable. Results are compared with results from groups not exposed to the variable.
Experimental Designs, often called true experimentation, use the scientific method to establish cause-effect relationship among a group of variables in a research study. Researchers make an effort to control for all variables except the one being manipulated (the independent variable). The effects of the independent variable on the dependent variable are collected and analyzed for a relationship.
When deciding on the appropriate approach, the from Ebling Library may be helpful. The following video, Quantitative Research Designs, further describes the differences between quantitative research approaches and offers tips on how to decide on methodology.

Discussion Questions (DQ)
- Initial responses to the DQ should address all components of the questions asked, include a minimum of one scholarly source, and be at least 250 words.
- Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source.
- One or two sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words.
- I encourage you to incorporate the readings from the week (as applicable) into your responses.
- Your initial responses to the mandatory DQ do not count toward participation and are graded separately.
- In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies.
- Participation posts do not require a scholarly source/citation (unless you cite someone else’s work).
- Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.
APA Format and Writing Quality
- Familiarize yourself with APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required).
- Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation.
- I highly recommend using the APA Publication Manual, 6th edition.
Use of Direct Quotes
- I discourage overutilization of direct quotes in DQs and assignments at the Masters’ level and deduct points accordingly.
- As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content.
- It is best to paraphrase content and cite your source.
- For assignments that need to be submitted to LopesWrite, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me.
- Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes.
- Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own?
- Visit the Writing Center in the Student Success Center, under the Resources tab in LoudCloud for tips on improving your paper and SI score.
- The university’s policy on late assignments is 10% penalty PER DAY LATE. This also applies to late DQ replies.
- Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances.
- If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect.
- I do not accept assignments that are two or more weeks late unless we have worked out an extension.
- As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.
- Communication is so very important. There are multiple ways to communicate with me:
- Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class.
- Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
