AP PSYCHOLOGY

Detailed explanation-1: -A within-subjects design is also called a dependent groups or repeated measures design because researchers compare related measures from the same participants between different conditions.

Detailed explanation-2: -Repeated Measures design is an experimental design where 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. Repeated Measures design is also known as within groups, or within-subjects design.

Detailed explanation-3: -A repeated-measures design is one in which multiple, or repeated, measurements are made on each experimental unit. The experimental unit could be a person or an animal, and repeated measurements might be taken serially in time, such as in weekly systolic blood pressures or monthly weights.

Detailed explanation-4: -Between-subjects (or between-groups) study design: different people test each condition, so that each person is only exposed to a single user interface. Within-subjects (or repeated-measures) study design: the same person tests all the conditions (i.e., all the user interfaces).

Detailed explanation-5: -In within-subject designs, participants are exposed to several levels of the same independent variable. This prior exposure to a treatment condition could alter the outcomes of later treatment conditions.
