Document Summary

Exposing participants to more than one level of the independent variable more than once. Allows you to see if the dv changes throughout the experiment. If going through all the levels does not take long than why not collect as much as data as you can so might as well. If you a small n this designs increases the amount of data you can collect. You may want to assess consistency across a variable to see if there is any change in the dv ex. Abba design: present all levels of the iv in one order and then in the mirror order. Within groups you create blocks of randomly ordered levels, and one participant does the whole block. Each block has all levels of the iv in some random order that is re-randomized again and again for each participant, and each time that the participant is exposed to the iv (ex.
