Part I: These are two separate questions therefore please do not combine the two questions together. For example: Q1, Q2, with in-text citation from course reading material listed below as references. 1. Two additional references are required. 2. In-text citation on every paragraph. 3. Please label all subheading. 4. APA formatting and style. My professor reviews my paper and will provide feedback and he usually requires for addition clarification in regards to what have been written. Therefore, I will forward to you the question(s) from my professor. Please answer the question(s) accordingly. Per class requirement, all papers must be submitted to Smarthinking for review before I can submit it in therefore please revise the paper according to Smarthinking suggestion.
Part II- Response Guidelines
After reviewing the discussion postings, respond to two peers:
• Follow the persistent link to the article being discussed.
• Using the language of research, explain how you agree or disagree with your peer’s evaluation, offering your own suggestions for improving the research design.
Readings
Read the introduction to Unit 4, Quantitative Methods: Experimental and Quasi-Experimental Approaches. This reading will introduce you to the defining characteristics of experimental and quasi-experimental approaches.
Note: This course, as well as other courses and other academic sources, uses the term "approach" to specifically refer to the major types of either methodology (qualitative methodology or quantitative methodology). For example, you have learned that there are three quantitative approaches: experimental, quasi-experimental, and non-experimental. Variations within each approach are called "designs," such as "simple time-series design." Some sources, such as Trochim’s Research Methods Knowledge BaseWeb site, use the term "design" in a broader way than this course does, using it to refer to an "approach" as well. In this course, "approach" will refer to the major types of each methodology, and "design" will be subtypes of the approaches.
Use your Leedy and Ormrod text to complete the following:
• Read Chapter 9, "Experimental, Quasi-Experimental, and Ex Post Facto Designs," pages 226–256. This chapter discusses the differences in experimental and quasi-experimental approaches, as well as specific designs for each approach. The chapter includes diagrams and examples to illustrate the various designs.
Use the Internet to complete the following:
• On Trochim’s Research Methods Knowledge Base Web site, read the pages listed below. These present additional information to aid your understanding of the experimental and quasi-experimental approaches.
o Introduction to Design.
o Types of Designs.
o Experimental Design.
o Quasi-Experimental Design.
Readings for Discussion
Use the library to locate two articles from the professional psychological literature that utilize quantitative methods. One of the articles should use an experimental approach, and the other article should use a quasi-experimental approach. The Finding Articles by Type: Experimental Research and Finding Articles by Type: Quasi-Experimental Research guides will show you some techniques for searching for experimental and quasi-experimental articles in the library databases:
Record the persistent link for each article found within the library databases. The persistent link is different from the URL in the browser window. Use this guide to learn where to locate your articles’ persistent links: Persistent Links and DOIs.
Read each article in preparation for this unit’s discussions.
Use Finding Articles for Your Discussion Post to learn how to locate articles within the library databases. This guide will walk you through the basic steps of accessing the library databases and creating a search strategy to find articles.
Q1- Quantitative Research: Experimental Research
For the experimental study you selected in this unit’s Studies, the Readings for Discussion section, complete the following:
1. Describe the variables (independent and dependent) used in the research.
2. Describe the treatment conditions of the experimental group.
3. Describe the specific type of research design that was used and discuss why it is considered experimental.
4. Evaluate the scientific merit of the selected design. How might you have designed this study differently? Evaluate how well the experimental approach and design helped the researcher answer the research questions.
5. List the persistent link for the article in your response. Refer to the Persistent Links and DOIs guide (linked in Resources) to learn how to locate this information in the library databases.
Response Guidelines
After reviewing the discussion postings, respond to two peers:
• Follow the persistent link to the article being discussed.
• Using the language of research, explain how you agree or disagree with your peer’s evaluation, offering your own suggestions for improving the research design.
Q2- Quantitative Research: Quasi-Experimental Research
For the quasi-experimental study you selected in this unit’s Studies, the Readings for Discussion section, complete the following:
1. Describe the variables (independent and dependent) used in the research.
2. Describe the different groups or conditions that were compared.
3. Describe the specific type of research design that was used, and discuss why it is considered quasi-experimental.
4. Evaluate the scientific merit of the selected design. How might you have designed this study differently? Evaluate how well the quasi-experimental approach and design helped the researcher answer the research questions.
5. List the persistent link for the article in your response. Refer to the Persistent Links and DOIs guide (linked in Resources) to learn how to locate this information in the library databases.
Response Guidelines
After reviewing the discussion postings, choose two peers to respond to:
• Follow the persistent link to the article being discussed.
• Using the language of research, explain how you agree or disagree with your peer’s evaluation, offering your own suggestions for improving the research design.
