Detailed explanation-1: -1. Independent measures / between-groups: Different participants are used in each condition of the independent variable. 2. Repeated measures /within-groups: The same participants take part in each condition of the independent variable.
Detailed explanation-2: -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.
Detailed explanation-3: -In a true experiment, the effect of an intervention is tested by comparing two groups. One group is exposed to the intervention (the experimental group, also known as the treatment group) and the other is not exposed to the intervention (the control group).
Detailed explanation-4: -The two basic two-group designs are the pretest-posttest control group design and the posttest-only control group design, while variations may include covariance designs.
Detailed explanation-5: -Independent groups design is an experimental design where different participants are used in each condition of the experiment.
