Psychology- Researvch Methods

Prior to beginning work on this coursework, read sections 1.2, 1.3, 2.1, and 5.2 in the Newman (2016) textbook and the instructor guidance for the week. This discussion has two parts. In Part 1, base your response on this week’s instructor guidance as well as the required sections of the textbook listed above. Compare and contrast characteristics of qualitative and quantitative research approaches, including such aspects as sample size and type of data. Briefly explain the difference between experimental and non-experimental research. In Part 2 , use the Ashford University Library to investigate one of the following research design categories based on the first letter of your last name: M-R: Correlational Research Sources for this part of the post can be found in the Research Methods research guide list of suggested articles. You may also search the University Library databases for articles about your research design category. Become an expert on your assigned category of research so you can explain it to others. In Part 2 of your post, • Explain the characteristics and purposes that define the research category. • Briefly describe some of the data collection and data analysis methods that are used in this type of research. • Mention one or more of the specific research designs that fall into your category. • Suggest a research topic for which this type of research would be suitable. • Use at least two scholarly/peer-reviewed sources and document them in APA style, with in-text citations and references listed at the end of the post. Another way of categorizing research designs is by whether they use qualitative or quantitative methods. The textbook provides some insight into the similarities and differences between these two approaches, but the following are additional characteristics to look for as you decide how to classify the methods used in a study. Qualitative research: • Relatively small sample sizes • Uses purposeful (specific) sampling to get participants who have knowledge and experience of the topic of the research • Narrative data (words, pictures, etc.) • Starts with a broad research question but may end with a hypothesis • Uses special coding methods for data analysis • Value is based on trustworthiness Quantitative research: • Relatively large sample sizes • Sampling techniques may be random to get a wide variety of participants representing the population • Numerical data in the form of variables • Hypothesis and/or research question(s) must be specified before data collection • Uses statistical techniques for data analysis • Value is based on validity and reliability Additional features of qualitative and quantitative research can be found at James Neill’s website, http://wilderdom.com/research/QualitativeVersusQuantitativeResearch.html (Links to an external site.)Links to an external site.
