What are the main types of qualitative approaches to research? Show
While there are many different investigations that can be done, a study with a qualitative approach generally can be described with the characteristics of one of the following three types: Historical research describes past events, problems, issues and facts. Data are gathered from written or oral descriptions of past events, artifacts, etc. It describes “what was” in an attempt to recreate the past. It is different from a report in that it involves interpretation of events and its influence on the present. It answers the question: “What was the situation?” Examples of Historical Research:
Ethnographic research develops in-depth analytical descriptions of current systems, processes, and phenomena and/or understandings of the shared beliefs and practices of a particular group or culture. This type of design collects extensive narrative data (non-numerical data) based on many variables over an extended period of time in a natural setting within a specific context. The background, development, current conditions, and environmental interaction of one or more individuals, groups, communities, businesses or institutions is observed, recorded, and analyzed for patterns in relation to internal and external influences. It is a complete description of present phenomena. One specific form of ethnographic research is called a case study. It is a detailed examination of a single group, individual, situation, or site. A meta-analysis is another specific form. It is a statistical method which accumulates experimental and correlational results across independent studies. It is an analysis of analyses. Examples of Ethnographic Research:
Narrative research focuses on studying a single person and gathering data through the collection of stories that are used to construct a narrative about the individual’s experience and the meanings he/she attributes to them. Examples of Narrative Research:
Treatment(s)The word treatment appears many times in the typical text on statistics and/or research design. It appears frequently in the indices of such texts. It is rarely defined. It is defined here, and how the term is used by researchers is shown. Treatments, Treatment Effects, Independent Variables, and Experimental ResearchResearchers are most likely to use the word treatment when referring to experimental research, especially when the data from that research were analyzed via analysis of variance (ANOVA). In experimental research, the researcher manipulates the independent or treatment variable(s) and then observes whether the treatment groups differ on one or more dependent or outcome variables.

What is the treatment in experimental research?The treatment is any independent variable manipulated by the experimenters, and its exact form depends on the type of research being performed. In a medical trial, it might be a new drug or therapy. In public policy studies, it could be a new social policy that some receive and not others.
Which variable is the treatment or intervention in a study?A manipulated independent variable exists when any type of treatment or intervention is used in a research study, be it a massage modality, an instructional method, a drug dosage, a medical procedure, or a psychotherapeutic intervention.
What is introduction in experimental research?Introduction. The introduction in an experimental article should follow a general to specific pattern, where you first introduce the problem generally and then provide a short overview of your own study. The introduction includes three parts: opening statements, literature review, and study overview.
