Document Summary
Experiment design: internal & external validity: experiment designs that vary levels of the focus variable only across subjects are called between-subject designs, and those who use several different levels for each subject are called within-subject designs. Between subjects each subject receives one treatment. Within subjects one subject receives all treatments. E. g. test levels of old vs new soles you can give some boys old material, and others new material to test the differences. However, to account for the differences in lifestyles between subjects, you could conduct a within-subject design by placing one shoe with old and the other with new. This helps to eliminate noise, or the differences between people. Problems with within-subject experiments learning over many trials, order effects, easier identification of experimenter demand. Consider both strong and weak: d, d, niederle and vesterlund found that although there are no gender differences in performance, more men choose tournament rather than women.
