Eveland's research design is quasi-experimental. The sample populations for the experiment are not randomly selected. There is structure to the experiment with more than one form of measurement during the research process. Quasi-experimental design includes multiple groups and multiple waves of measurement. While there were not a significant number of groups in the experiment, there was more than one. At more than one point in the experiment, measurements were taken.

According to researchers such as Trochim, there are a few different types of research design. A randomized experiment is just that -- it is a random assignment which is different from random selection. Random assignment is a way in which comparison in experiments may be better facilitated because it helps create similar groups within the experiment population. If there are any differences among the population it is because of chance and not because of some kind of manipulation or premeditation...
