What are quasi-experimental designs? Why are they important?

PSYCH 540 Week 4 Complete Discussion 1.To illustrate this, how about going to the library in one of the psychological databases (e.g. Proquest, PsycINFO, etc.) or going to Google Scholar and finding an article that reports on either a case study or a small-n experimental design study? Discussion 2.Design an imaginary quasi-experimental study. Give us a brief description of your study, then answer as many of the following questions as you care to: 1. What is the hypothesis of your imaginary study? 2. What is/are the independent variable(s)? 3. What is/are the dependent variable(s)? 4. Briefly, how will you test your hypothesis? That is, what are the procedures you will use in your study? 5. What led you to your hypothesis; that is, what makes you think that changing the independent variable(s) will cause a change in the dependent variable(s)? 6. Now comes the fun question: Why could this study not be conducted with a true-experimental design? Learning Team Assignment – Research Project: Experimental Method Design Utilizing experimental research methods, design a research study for the issue that you selected for your Research Projects and write a research article reporting on your study as if you had actually conducted it. • Your paper, citations, and reference list need to be formatted properly in APA format. • (NOTE: THIS ASSIGNMENT MUST USE EXPERIMENTAL METHODS.) As a part of your research study be sure to address the following items: • a. State the experimental hypothesis that your study tested. • b. Describe your sample population in detail (selection method, size, composition, any incentives offered, etc.). • c. Describe the experimental method(s) that you selected to utilize in your research study and explain why you selected these methods. Describe fully your methods, procedures, variables, and instruments used to measure changes in the variables. • d. Describe your data analysis methods, including the inferential statistics you used. • e. Describe the results of the experiment (these are imaginary results you will come up with based on the methods and data analysis). As with last week’s project, there is no word count for this assignment. It will be graded based on comprehensiveness and thoroughness in creating a scholarly/professional report of your descriptive methodology study you created within your group imagination AND the coherence and cohesiveness of all the elements in the study (meaning, it all fits together as one study). Use APA format for structure of the paper, citations, and reference list. Click the Assignment Files tab to submit your assignment. Individual Assignment – Applied Research Questions Using the University Library, the text, AND other resources (making sure they are all scholarly sources!) and citing these sources in your paper, answer the following questions. Your response to each bullet point group of questions should be at least 400 words in length. Use proper APA format in writing your paper, though an introduction and conclusion are not required. • What are descriptive statistics and what are inferential statistics? What are the similarities between descriptive and inferential statistics? What are the differences? • What are the similarities between descriptive single-case designs (which are qualitative studies, like case studies are) and small-N research designs? What are the differences? When should descriptive single-case designs be used and when should small-N research designs be used? • What are true experiments? How are threats to internal validity controlled by true experiments? • What are quasi-experimental designs? Why are they important? How are they different from experimental designs?

What are the different types of correlation? Now for the technical area: How is the strength of a correlation determined?

PSYCH 540 Week 5 Discussion 2 1.The subject of this question is measures of central tendency. (Let- not bother with mode because it will rarely come up in real life.) This is THE basic part of any quantitative study- data analysis. Let- make sure we’re clear about what the mean and what the median are. Does all data have a mean and a median? Why or why not? When is the mean the best measure of central tendency? When is the median the best measure of central tendency? Now for an important part of many studies: what is the standard deviation? (Don’t be shy about giving this a try; we’ll help with explanations.) Why is sd (standard deviation) such an important term? 2. Now for correlations. The concept behind the word correlations is good to know well because it is the foundation of most studies: we see correlations between things and we wonder how these correlations work a lot as professionals. What are the different types of correlation? Now for the technical area: How is the strength of a correlation determined?

Define the word teratogen and summarize the factors that affect the impact of teratogens on prenatal development

PSYCH 500 Week 2 Complete Discussion 1. Define the word teratogen and summarize the factors that affect the impact of teratogens on prenatal development. Give at least 2 examples and discuss the evidence supporting the harmful impact of each. Discussion 2.Describe and interpret the relationship between secure attachment in infancy and later development. Individual Assignment – Field Research Consider the following: Many products, diets, and services are marketed to parents as beneficial to infant or toddler development. In order to increase sales to parents and caretakers, some companies use marketing strategies that make exaggerated, unfounded, or unrealistic claims about the effects of their product(s) on child development. Select one claim that you suspect to be exaggerated or false (your research may in fact show the claim has validity). Describe in detail what the advertised product, diet, or service is supposed to do. Some examples are: • Educational videos as related to language development • Effects of classical music on cognitive development • Benefits of soy diet or organic food diet on physical and cognitive development • Service promising to teach your 18-month-old how to read • Any other claim made by a manufacturer or service provider, aimed at enhancing infant or toddler development Write a 1,400- to 1,650-word paper addressing the following: • What area or areas of development does the product, diet, or service claim to enhance? • Use the UoPX library to investigate the claim. What does the published literature say about the issue or concern that you are investigating? What does the research reveal about how to promote healthy development in this area or areas? What does this reveal about the necessity and actual benefits of the product, diet, or service? • Is there any evidence to support the claim? Why or why not? • Imagine that a licensed psychologist in your state publically endorsed a product with no empirical evidence supporting its claims. It was later discovered that the psychologist was receiving a percentage of money from the sale of the product to parents. Is this a violation of the APA code of ethics? Explain. Be sure to cite the appropriate section or sections of the Code in your response. Investigate the claim using your textbook and a minimum of four additional scholarly sources (such as peer reviewed journal articles). Format your paper according to APA guidelines. Note: You may not find a peer-reviewed journal article on a specific product, diet, or service. However, you will most likely be able to find peer-reviewed journal articles on the general issue that you are investigating. For example, if you are investigating educational videos that claim that cognitive skills in infancy are enhanced by using a particular approach or method, you can then review and evaluate studies that focus on enhancing cognitive skills in infancy. Review the evidence for and against the use of specific techniques and summarize your findings. Click the Assignment Files tab to submit your assignment.
