A quasi-experimental design is a design that resembles and experimental design but does not have the key ingredient of random assignment. They involve selecting groups that are used to test a variable but with no random pre-selection process.

In experimental design, the null hypothesis serves as a foundational statement that posits no effect or no difference between groups or conditions. It provides a baseline against which researchers can compare their experimental results. By testing the null hypothesis, researchers can determine whether observed effects are statistically significant or could have occurred by chance. If the null hypothesis is rejected, it suggests that there is enough evidence to support an alternative hypothesis.
Pre-experimental research designs are research designs that are characterized by a lack of random selection and assignment.
