Qualitative, quantitative and mixed methods dissertations What are they and which one should I choose?
Approaches in Psychology Research[ edit ] Nomothetic Quantitative Approach [ edit ] This approach is basically used in inferential and descriptive statistics as both mediums of scientific method of investigation in analyzing, presenting, and interpretation of data gathered by the researcher through standardized or objective instruments e.
Psychologists who adopt this approach are mainly concerned with studying what we share with others. That is to say in establishing laws or generalisations. Carl Dellomos, Idiographic Qualitative Approach [ edit ] This approach tends not to use inferential or descriptive statistics, but rather uses qualitative methods of data gathering such as interviews, diaries, and other written materials, obtained from or provided by the expected or anticipated respondents of a particular research.
Psychologists interested in this aspect of experience seek to discover what makes each of us unique. Despite the importance of our genetic individuality, proceeding from biology, the distinction between the nomothetic and the idiographic is often equated with two types of science — the natural sciences concerned with discovering laws of nature, and the social sciences concerned with individual meanings.
We can examine these differences further by seeing how they relate to personality theory. Carl Dellomos, Both approaches were introduced by Gordon Allport.
Carl Dellomos, Research Designs[ edit ] Although there are many different kinds of research designs in psychology, studies may be categorized into descriptive or qualitative, correlational, and experimental.
The method of data collection also varies, with self-report on one end of the spectrum, and naturalistic observation on the other. Descriptive Studies[ edit ] The Studies that do not test specific relationships between variables are called descriptive studies.
In this research method, general or specific behaviors or attributes are observed and measured, without respect to each other.
These studies are generally the design of choice for breaking into new areas, as the vast but often inconclusive amount of information collected can be drawn upon for future hypotheses. An example of such a study would be a researcher inquiring into the quality of mental health institutions. This would be done by observation or measurements of various criteria, as opposed to relationships between variables.
Alternatively, the study could be conducted without any specific criteria in mind. Correlational Study[ edit ] This method of statistical analysis shows the relationship between two variables.
For example, research has shown that alcohol dependence correlates with depression. That is to say, the more alcohol people consume, the more depressed they become. On the other hand, it could be the other way around as well: The attributes of correlations include strength and direction.
The direction may be positive both variables both increase or decrease togethernegative one variable increases while the other decreases or unrelated a random relationship between variables. This is so because a third variable could be shown to cause the occurrence of one of the variables.Types of Research Methods Adapted from Edvantia SBR Rating for Technical Assistance Programs and Services form () and Carter McNamara Overview of Methods to Collect Information handout.

Resolving discrepancies between different types of data. Some designs generate unequal evidence. Characterized by: A nested approach that gives priority to one of the methods and guides the project, while another is embedded or “nested.” vetconnexx.com · Observational research: There are many types of studies which could be defined as observational research including case studies, ethnographic studies, ethological studies, etc.
