Question

Quizplus · Accepted Answer

Quasi-experimental designs are research designs that do not involve random assignment of participants to groups, but may still involve manipulation of an independent variable and measurement of a dependent variable. Nonrandomized experimental designs and pseudo-experimental designs also do not involve random assignment, but the term "quasi-experimental" is more commonly used in psychology research. Correlational designs do not involve manipulation of variables, and simply measure the relationship between variables that already exist.
