What is an independent subject design?

1. Independent Measures: Independent measures design, also known as between-groups, is an experimental design where different participants are used in each condition of the independent variable. This means that each condition of the experiment includes a different group of participants.

What is an example of an independent measures design?

An independent measures design is a research method in which multiple experimental groups are used and participants are only in one group. Each participant is only in one condition of the independent variable during the experiment. An example would be a drug trial for a new pharmaceutical.

What is the independent variable in the study for a between subject design?

Using a between-subjects design Every experimental group is given an independent variable treatment that the researcher believes will have some effect on the outcomes, while control groups are given no treatment, a standard unrelated treatment, or a fake treatment.

What is the independent variable in a single subject design?

• Independent Variable (IV): The treatment or procedure that the experimenter controls – the treatment or procedure being used to change behavior. o Typically, in single-subject studies, the categories of the IV reflect the phases of. the treatment or lack of treatment.

What are the limitations of independent measures design?


  • researcher cannot control the effects of participant variables (i.e. different characteristics or abilities of each participant). This would cause a confounding variable.
  • needs more design than the Repeated Measures Design in order to end up with the same amount of data.

What is an independent variable in psychology?

The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.

What is an example of a single subject design?

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 are the types of single subject design?

Principal methods in this type of research are: A-B-A-B designs, Multi-element designs, Multiple Baseline designs, Repeated acquisition designs, Brief experimental designs and Combined designs. These methods form the heart of the data collection and analytic code of behavior analysis.

What is the benefits of subject design?

Perhaps the most important advantage of within-subject designs is that they make it less likely that a real difference that exists between your conditions will stay undetected or be covered by random noise. Individual participants bring in to the test their own history, background knowledge, and context.
