What are the main differences between experimental and quasi-experimental studies?
What will be an ideal response?
The main distinction between experimental and quasi-experimental research lies in the allocation of persons to groups. In traditional experimental research persons are
allocated to groups through randomisation, to minimise bias. Quasi-experiments are often used precisely because such random allocation is not possible or practical.
Typically, the experimental group will be decided by which settings (e.g. schools/classrooms/factories) have volunteered or been selected to be part of the intervention. Therefore, rather than randomly allocating, we will have to choose a
control group that is as similar to the experimental group as possible. Because we are not using random allocation, we call this control group the comparison group, as it is not
a pure control group. This means that there is a greater likelihood of bias in quasiexperimental research.
