Quasi-experimental designs are used when full manipulation of scheduling or allocation of treatments to test units is not possible, but some aspects of true experimentation can still be applied. This type of design is often used in real-world settings where full control over experimental conditions is not feasible. True experimental designs require complete control over all aspects of the experiment, while preexperimental designs do not involve a control group or randomization of subjects. Statistical designs can refer to any type of experiment that uses statistical analysis, so this answer is too broad.
