Answer :

A quasi-experimental research design used to study changes across the lifespan by observing the same participants at different points in time and measuring the same dependent variable at each time is called a longitudinal design.

A quasi-experimental research design similar to true experiment attempts to establish a cause-and-effect relationship between an independent and dependent variable. However, unlike a true experiment, a quasi-experiment does not depend on random assignment rather subjects are assigned to groups based on non-random criteria.

Longitudinal design is a quasi-experimental research design that involves repeated observations of the same variables over short or long periods of time. It is used to establish relationships between variables that are not related to various background variables and involves studying the same group of individuals over an extended period.
