Experimental Research Designs Flashcards
When using a___groups research design,the effects of anindependent variable are assessed by administering each level of the indepedent variable to a different___of subjects and comparing the performance or status of the groups on the____variable.
between; group;dependent
When using a___subjects(repeated measures)design,the effects of an independent variable are analyzed by comparing the performanceor status of the same group of subjects on the___variable after receiving, at different times each level of the independent variable.
within-;dependent
In the single-group____design the dependent variable is measured several times both before and after the independent variable is applied.
time-series
A research design that includes two or more independent variables is called a ___design.An advantage of this type of design is that it allows an investigator to assess the___effects of each independent variable as well as any___between those variables.
factorial; main;interaction
Two distinguishing characteristics of the single-subject designs are that they include at least two phases–a___(no treatment) phase and a____phase—and thatthey involve measuring the____variable at regular intervals during each phase ofthe study.
baseline;treatment;dependent
Three commonly-used singlesubject designsare the AB design, the reversal design and the multiple baseline design. The AB design includes one_____(A) phase and one___(B) phase. The reversal designsextend the AB design by including at a minimum two___phases and one___phase.
baseline;treatment;baseline; treatment
When using a reversal design,if the subject’s performance on the___variable follows the predicted pattern(i.e., ifit changes in the expected directionafter the treatment is applied and withdrawn), a researcher can conclude that changes in the___variable are due to the___variable rather than to history.
dependent; dependent; independent
When it is not ethical or practical to withdraw an effective treatment an investigator can use the multiple___design which involves sequentially applying the__variable to two or more”baselines”-i.e., either to two or more behaviors, settings,or subjects. An Advantage of this design is that once the IV is applied to a baseline it is not__during the study.
