Question

Quasi-experimental designs are used when true experimental designs are not possible or ethical. They lack random assignment and control over extraneous variables, but still allow for the investigation of cause and effect relationships between independent and dependent variables. Single-case experimental, multiple baseline, and interrupted time series designs are all specific types of quasi-experimental designs.
