Quasi Experiment

Not true experiments because they lack control over the groups

Lack of random allocation:

• at times it is not possible for an experimenter to randomly allocate participants to groups

  Eg. if one of the variables is male or female, this can not be randomly allocated

• It is quasi id it lacks random allocation to groups but is like a true experiment in most other ways

Examples:

Studies that include types of personalities

Comparison of people with a psychological disorder to those that do not

Such studies can not randomly allocate people to groups

Quasi vs lab:

Quasi could take place in a lab and all other aspects of research could be controlled
