Document Summary

Topic 4: true experiments - one variable designs (part 2) --> Within subjects designs when a variable is manipulated within subjects, all subjects receive all levels of that variable a given study can use: only between groups variables only within-subjects variables or a combo of the two. **the variable is within subjects, not the experiment. Complete within subjects designs participants get each treatment often enough to balance stage of practice e ects for each subject remedies for stage practice e ects. Block randomization each block of trials contains one trial for each treatment number of blocks = number of times each treatment occurs order of treatments randomized within a block works well with many trials per treatment. ** the is different from lock randomization sued to assign subjects to treatments in the between groups designs we are using block randomization to assign trials to treatments within one subject.
