Answer:
Longitudinal designs
Explanation:
Longitudinal design is the term used to describe the situation in which the characteristics of an individual are measured and evaluated when these individuals are subjected to two or more different situations. Longitudinal design is an observational study in which data from the same sample is collected repeatedly over an extended period of time, as is the cross-sectional study. For this reason, we can conclude that longitudinal designs provide ways in which correlational researchers can attempt to demonstrate causal relationships between variables, even though the causal relationship may still be somewhat uncertain.
