Quasi-experimental research

Quasi-experimental research

These are similar to experiments but without random assignment to the groups. There is a lack of internal validity - how can we be sure that x caused y if there was some engineering of the groups?

There are two main types:

  • non-equivalent control group
  • before-and-after
