What is a single study called?
“Single subject research (also known as single case experiments) is popular in the fields of special education and counseling. This research design is useful when the researcher is attempting to change the behavior of an individual or a small group of individuals and wishes to document that change.
What is a single subject design in research?
Description. Single subject research design is a type of research methodology characterized by repeated assessment of a particular phenomenon (often a behavior) over time and is generally used to evaluate interventions [2].
What is a single subject design example?
For example, a researcher might establish a baseline of studying behaviour for a disruptive student (A), then introduce a treatment involving positive attention from the teacher (B), and then switch to a treatment involving mild punishment for not studying (C).
What is an example of single variable research?
The first thing that is likely to occur to these researchers is to obtain a sample of middle-school students who have been bullied and then to measure their self-esteem. But this design would be a single-variable study with self-esteem as the only variable.
What is a single group study?
We define a single group study as a study that consists of only a single group of subjects included in the study design, in which all subjects received a single intervention and the outcomes are assessed over time (i.e., not a cross-sectional study).
When would you use a single case study?
If the researcher only wants to study one single thing (for example a person from a specific group) or a single group (for example a group of people), a single case study is the best choice (Yin, 2003).
How do you create a single-subject study?
A single-subject research design that begins with a baseline condition with no treatment, followed by the introduction of a treatment, and after that a return to the baseline condition. It can include additional treatment conditions and returns to baseline.
Is single research design suitable for all studies?
Single research design is not suitable for all studies since it only involves evaluation & assessment of individual cases (oftenly behavior). Thus, they are only ideal in the fields of psychology and education.
What type of statistical approach is used for single-subject research?
Data Analysis in Single-Subject Research Group data are described using statistics such as means, standard deviations, Pearson's r, and so on to detect general patterns. Finally, inferential statistics are used to help decide whether the result for the sample is likely to generalize to the population.
What is the difference between a single and multiple case study?
Single case study: This type of case study focuses on one group, person, or event. Multiple case study: In this type of case study, the researcher studies two or more cases.
What is meant by single variable?
The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution. For example, 2x+3=8 is a linear equation having a single variable in it. Therefore, this equation has only one solution, which is x = 5/2.
What is a single variable data?
Single variable data is usually called univariate data. This is a type of data that consists of observations on only a single characteristic or attribute.
What is single subject research?
This research design is useful when the researcher is attempting to change the behavior of an individual or a small group of individuals and wishes to document that change. Unlike true experiments where the researcher randomly assigns participants to a control and treatment group, in single subject research the participant serves as both the control and treatment group. The researcher uses line graphs to show the effects of a particular intervention or treatment. An important factor of single subject research is that only one variable is changed at a time. Single subject research designs are “weak when it comes to external validity….Studies involving single-subject designs that show a particular treatment to be effective in changing behavior must rely on replication–across individuals rather than groups–if such results are be found worthy of generalization” (Fraenkel & Wallen, 2006, p. 318).
Why do researchers use line graphs?
The researcher uses line graphs to show the effects of a particular intervention or treatment. An important factor of single subject research is that only one variable is changed at a time.
What is single subject research?
Single-subject research—which involves testing a small number of participants and focusing intensively on the behaviour of each individual— is an important alternative to group research in psychology. Single-subject studies must be distinguished from case studies, in which an individual case is described in detail.
How many participants are in a single subject study?
Note that the term single-subject does not mean that only one participant is studied; it is more typical for there to be somewhere between two and 10 participants. (This is why single-subject research designs are sometimes called small- n designs, where n is the statistical symbol for the sample size.)
What is qualitative research?
A type of quantitative research that involves studying the behaviour of each small number of participants in detail. The study of large numbers of participants and examining their behaviour primarily in terms of group means, standard deviations, and so on. A detailed description of an individual, which can include both qualitative ...
Why is it important to focus on the behaviour of individual participants?
One reason for this is that group research can hide individual differences and generate results that do not represent the behaviour of any individual.
What is a case study?
A. case study. is a detailed description of an individual, which can include both qualitative and quantitative analyses. (Case studies that include only qualitative analyses can be considered a type of qualitative research.)
What is the second assumption of single subject research?
A second assumption of single-subject research is that it is important to discover causal relationships through the manipulation of an independent variable, the careful measurement of a dependent variable, and the control of extraneous variables.
Why are case studies important?
One reason is that case studies usually do not allow researchers to determine whether specific ...

Single-subject research—which involves testing a small number of participants and focusing intensively on the behavior of each individual —is an important alternative to group research in psychology. Single-subject studies must be distinguished from qualitative research on a single person or small number of individuals.

For this reason, single-subject research is often considered a type of experimental research ...
What is qualitative research?
More broadly speaking, qualitative research focuses on understanding people’s subjective experience by observing behavior and collecting relatively unstructured data (e.g., ...
Why is it important to focus on the behavior of individual participants?
One reason for this is that group research can hide individual differences and generate results that do not represent the behavior of any individual.

Who was the first psychologist to study consciousness?
In the late 1800s, one of psychology’s founders, Wilhelm Wundt, studied sensation and consciousness by focusing intensively on each of a small number of research participants. Herman Ebbinghaus’s research on memory and Ivan Pavlov’s research on classical conditioning are other early examples, both of which are still described in almost every ...
Is single subject research qualitative?
But single-subject research is an important alternative, and it is the primary approach in some more applied areas of psychology. Before continuing, it is important to distinguish single-subject research from case studies and other more qualitative approaches that involve studying in detail a small number of participants.
Need for Blind Experiment
Consider an example to understand why blind experiments are important. A food company has developed a new cereal. It has a similar appearance and taste to another popular cereal, but this cereal has fewer calories, less sugar, and more nutrients.
Single-Blind Procedure
In a single-blind procedure, the researchers get a group of volunteer participants. They are told of the possible risks and potential benefits but also that they won't know which group they are placed in. The participants must all sign consent forms agreeing to the experiment.
Single-Blind Study Example
Another example of a single-blind study is trying a new hand lotion. Each participant would be assigned to either the control or the experimental group. The control group would get a known hand lotion, while the experimental group would try the new hand lotion.
What are the different types of research studies?
The five types of studies are discussed below. 1. Case Studies. Case studies look at a single subject (e.g., a child with autism) or a single case (e.g., a classroom for children with autism). Case studies are typically used in research ...
What are the two types of experimental studies?
Two primary types of experimental studies are used in intervention development and testing: randomized group design and single-case design.
What are the advantages of randomized experimental studies?
The advantage of randomized experimental studies is that the research design allows researchers to examine cause-and-effect relationships.
What are the advantages of correlational studies?
The advantage of correlational studies is that a lot of information about a large number of people can be gathered at one point in time.
What is an uninformed state?
This uninformed state is what researchers refer to as being blind to the conditions of the experiment. When both participants and experimenters are uninformed, it is referred to as a double-blind study, and is a means of ensuring objective results.
What are the disadvantages of case studies?
The disadvantage of a case study is that the information gathered about one person or a small group of people cannot readily be applied or generalized to other people or other cases in other situations or other settings and, therefore, may be of limited use. Click here to check out a sample case study. 2.
What is longitudinal study?
Longitudinal Studies. Longitudinal studies can give us information about how people develop over time. These types of studies follow one group of people (referred to as a cohort) across time, measuring the same behavior multiple times.
What is the importance of single subject research?
Another important aspect of single-subject research is that the change from one condition to the next does not usually occur after a fixed amount of time or number of observations. Instead, it depends on the participant’s behaviour.
How does single subject research differ from group research?
In addition to its focus on individual participants, single-subject research differs from group research in the way the data are typically analyzed. As we have seen throughout the book, group research involves combining data across participants. Group data are described using statistics such as means, standard deviations, Pearson’s r, and so on to detect general patterns. Finally, inferential statistics are used to help decide whether the result for the sample is likely to generalize to the population. Single-subject research, by contrast, relies heavily on a very different approach called#N#visual inspection#N#. This means plotting individual participants’ data as shown throughout this chapter, looking carefully at those data, and making judgments about whether and to what extent the independent variable had an effect on the dependent variable. Inferential statistics are typically not used.
Can single subject research be analyzed?
The results of single-subject research can also be analyzed using statistical procedures— and this is becoming more common. There are many different approaches, and single-subject researchers continue to debate which are the most useful. One approach parallels what is typically done in group research.
