What type of research enables a researcher to determine if an association or relationship between two factors exists?

What are the main types of qualitative approaches to research?

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:

  • A study of the factors leading to the historical development and growth of cooperative learning
  • A study of the effects of the historical decisions of the United States Supreme Court on American prisons
  • A study of the evolution of print journalism in the United States through a study of collections of newspapers
  • A study of the historical trends in public laws by looking recorded at a local courthouse

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:

  • A case study of parental involvement at a specific magnet school
  • A multi-case study of children of drug addicts who excel despite early childhoods in poor environments
  • The study of the nature of problems teachers encounter when they begin to use a constructivist approach to instruction after having taught using a very traditional approach for ten years
  • A psychological case study with extensive notes based on observations of and interviews with immigrant workers
  • A study of primate behavior in the wild measuring the amount of time an animal engaged in a specific behavior

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:

  • A study of the experiences of an autistic student who has moved from a self-contained program to an inclusion setting
  • A study of the experiences of a high school track star who has been moved on to a championship-winning university track team

What kind of research determines the relationship or association between 2 factors?

A correlational research design investigates relationships between variables without the researcher controlling or manipulating any of them. A correlation reflects the strength and/or direction of the relationship between two (or more) variables. The direction of a correlation can be either positive or negative.

What is correlation in research?

According to the definition of correlational research, correlational research refers to a type of non-experimental research method that studies the relationship between two variables with the help of statistical analysis.

Which research method is the best to determine a causal relationship between 2 variables?

The use of a controlled study is the most effective way of establishing causality between variables. In a controlled study, the sample or population is split in two, with both groups being comparable in almost every way. The two groups then receive different treatments, and the outcomes of each group are assessed.

Why should a researcher determine the relationship between the two variables?

It is very important to understand relationship between variables to draw the right conclusion from a statistical analysis. The relationship between variables determines how the right conclusions are reached.
