Question

Quasi-experiments based on nonequivalent groups involve :

1 random assignment
2 matched groups
3 cyclical groups
4 unmatched groups

Answer 1

4. unmatched groups

Step-by-step explanation:

In Quasi experiments the assignment of unmatched or nonequivalent groups is the very bass of experimentation.

They are matched upon certain pre existing characteristics and then they are experimented upon to the certain criteria they are matched and unmatched to, and then are the results computed according to the unmatched groups that are divided for the experiment.
