What is an independent group design psychology?
The independent groups design is an experimental design whereby two groups are exposed to different experimental conditions. Usually half of the participants are assigned to the experimental group where they are exposed to a condition where the independent variable is manipulated.
What is an independent group design example?
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 independent groups between subjects design?
It’s the opposite of a within-subjects design, where every participant experiences every condition. A between-subjects design is also called an independent measures or independent-groups design because researchers compare unrelated measurements taken from separate groups.
What is an advantage of using independent groups design?
Independent groups design
| Independent groups design | |
| Advantages No order effects Lower risk of demand characteristics Same tests/materials can be used | Disadvantages Participant variables More participants required than with repeated measures design |
| Evaluation |
What is the main difference between independent groups and within groups designs?
In a within groups design they are exposed to all levels, in an independent groups design they are only exposed to one level. Participants are exposed to all the levels of an independent variable at roughly the same time, and a single attitudinal or behavioral preference is the dependent variable.
Why are independent groups used?
Independent Groups Design Data collection will be less time-consuming if all conditions of the experiment can be conducted simultaneously. Different participants need to be recruited for each condition, which can be difficult and expensive.
What is an independent design?
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 independent sample in psychology?
a process for selecting a sample of study participants from a larger potential group of individuals such that the probability of each person being selected for inclusion is not influenced by which people have been chosen already. The resulting samples will be independent samples.
What is between group design in psychology?
In the design of experiments, a between-group design is an experiment that has two or more groups of subjects each being tested by a different testing factor simultaneously.
What is two independent group design?
A two-group design is when a researcher divides his or her subjects into two groups and then compares the results. The two groups usually consist of a control group, who does not get the treatment, and a treatment or experimental group, who does get the treatment.
What are independent variables in psychology?
The independent variable is the variable that is manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.
Which of the following is an advantage of within subjects designs over independent groups designs?
What are some advantages of within groups designs? It ensures the participants in the two groups will be equivalent (because they are the same people). Variations among participants will not effect results because their scores are only rated against themselves and not others.
What is the independent groups design when designing a study?
Describe and evaluate the independent groups design when designing a research study (6). The independent groups design is an experimental design whereby two groups are exposed to different experimental conditions.
What is meant by within groups design?
This type of design is also known as within groups. The same participants take part in each condition of the independent variable. This means that each condition of the experiment includes the same group of participants.
What are the different types of Design in psychology?
Types of design include repeated measures, independent groups, and matched pairs designs. Probably the commonest way to design an experiment in psychology is to divide the participants into two groups, the experimental group, and the control group, and then introduce a change to the experimental group and not the control group.
What is independent measures design in psychology?
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.
