Detailed explanation-1: -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.
Detailed explanation-2: -In within-subjects experimental designs, each subject in the study is exposed to each level of the independent variable. Therefore, for each subject a score on the dependent variable is collected more than once (once for each level of the independent variable).
Detailed explanation-3: -Four major design types with relevance to user research are experimental, quasi-experimental, correlational and single subject. These research designs proceed from a level of high validity and generalizability to ones with lower validity and generalizability.
Detailed explanation-4: -By far the most common approach to including multiple independent variables in an experiment is the factorial design. In a factorial design, each level of one independent variable (which can also be called a factor) is combined with each level of the others to produce all possible combinations.
Detailed explanation-5: -Independent groups design is an experimental design where different participants are used in each condition of the experiment.
