Document Summary

Require fewer participants to obtain the same amount of data per condition. Deal with them by having more participants - extreme data points won"t have a great effect. Statistical power - easier to find statistical effect - larger. Equivalent groups - literally using the same people. Less set-up required; less resources required to prepare for participant. Special populations with low n - don"t need as many people with within-groups design. Only way of answering certain types of questions - when you have to compare different levels of a variable (i. e. Two ways of measuring the dv in within-groups design. Present all levels of iv before taking the dv (i. e. Drink all types of water, then ask which is preferred) Present one level of iv, then measure the dv, do it repeatedly (i. e. Interact with own child on one day and measure oxytocin levels, then interact with strangers child on another way and measure oxytocin levels)
