PSY-7106 Quantitative Research Design
Descriptive design records what is observed, described, and documented. This design does not establish causality; instead it only establishes that there is an association between variables. There is no experimental or random selection of groups. This involves collecting data that will provide a description of what is being studied. This can be a description of a sample, a group, a dataset, or circumstances. Some researchers refer to descriptive designs as descriptive nonexperimental research. Thinking back to our continuum, nonexperimental designs and experimental designs are different as only experimental designs can establish a causal relationship between variables so that relationships can be explained.
Descriptive design research typically does not begin with a hypothesis. Instead, the researcher normally develops one after data has been collected. This design follows a systematic collection of data. Some examples of descriptive research designs are a description of eating habits of adolescents; a description of the voting inclinations of older adults, or a description of the behaviors of youth in residential placement.
The research results of a descriptive design also employ descriptive statistics which describe the basic features of information in a study. These statistics include measures of central tendency, a description of the distribution of a sample, and measures such as the mean, median and mode.

Describing Descriptive Research
Warm-Up Activity 1.1: Complete Exercises
This week you will practice calculating the mean, median, and mode, and percentile ranks by completing the following exercises in your textbook. Once you are done, compare your answers against this week’s exercise answer guide, located under your weekly resources.
- Chapter 5 Exercises in Jackson (2016) questions 3 and 5 page 138.
- Chapter 11 Exercises in Trochim, Donnelly, & Arora, (2015) pages 302 and 303.
Spotlight on Skills: Academic Integrity
Throughout your coursework you will be asked to review the work of others, make critiques, and provide your own solutions to issues and problems related to the field. During this process you must be scrupulous in distinguishing between your work and the work of others. One way of doing this is through integrity in writing. Northcentral University considers it a violation of Academic Integrity to knowingly submit another person’s work and present it as that of the student’s, without properly citing the source of the work.
- Carefully note that Northcentral University’s Academic Integrity code requires not only that the student abstain from presenting the work of another as his or her own work, but also that the student properly cite the source of the work.
- Northcentral University considers it the responsibility of the student to become familiar with how to properly cite sources. All students are required to successfully fill out the Academic Integrity Questionnaire at the beginning of their course of studies, thus confirming their understanding of the Integrity policy and their commitment to adhering to that policy.
- Instructors are required to provide a sample of each student’s work to the turnitin service, which checks each paper for similarity to original works and papers turned in by students in hundreds of other universities.
- The student is responsible for understanding and adhering to the Academic Integrity Policy and for avoiding all instances of plagiarism in writing. Violations of the Northcentral University Integrity Code are reported by the Instructor to the School and a series of consequences follow, ranging from being required to revise the paper within 3 days (first violation only) to grade penalties, course failures, and dismissal from the university.
- APA Central offers several tutorials on scholarly writing. Explore these Tutorials within the Learn menu; you will need to create an account to access the material. Ethical Standards in Research and Writing and How to Avoid Plagiarism and Self-Plagiarism are recommended. APA Central also offers Self-Quizzes to check your knowledge.
Your task this week is to locate three peer-reviewed articles that report on studies conducted in psychology using descriptive design.
Then, evaluate and discuss the key points of each design (such as how the data are described; how the data are represented, etc.) from the three selected studies. Provide a detailed description of each study regarding the design that was utilized and the type of descriptive statistics that were conducted.
Finally, include the permalinks to, or copies of each study, for your instructor.
Length: 5-7 pages
Your paper should demonstrate thoughtful consideration of the ideas and concepts presented in the course by providing new thoughts and insights relating directly to the topic. Your response should reflect scholarly writing and current APA standards. Be careful to adhere to Northcentral’s Academic Integrity Policy.
