Randomly give treatment to some in the group and does not get the treatment to the others; a dependent (what changes or has an effect) and independent (what is controlled) variable. A quasi-experiment is similar to experiment except the groups are not randomly assigned.
Divide group into two teams and assign one as control and one as experiment.
