In quasi-experimental research,... Webbquasi-experimental, since randomization is ruled out unless the treatment had been randomized, but if the program designers had thought of that they will have thought of a baseline also), then a single difference estimate is in principle valid. 2. Find another data set to serve as a baseline. If there was a baseline WebbQuasi-experimental research (which will be described in more detail in a subsequent chapter) is in the middle because it contains some, but not all, of the features of a true experiment. For instance, it may fail to use random assignment to assign participants to groups or fail to use counterbalancing to control for potential order effects. chinese drums royalty free
