what kind of research is saanvi conducting if she tracks six groups of participants, each group a different age, over several years, assessing them on her variable of interest once every six months?

Saanvi is conducting a sequential research study. This type of research involves tracking multiple groups (cohorts) of participants of different ages over several years and assessing them repeatedly on the variable of interest at regular intervals (e.g., every six months). Sequential designs combine elements of both longitudinal and cross-sectional studies, allowing researchers to observe age-related changes over time while comparing different age groups simultaneously. This approach also helps to control for cohort effects and time-of-measurement effects, providing a more comprehensive understanding of developmental or age-related trends than either purely longitudinal or purely cross-sectional designs alone
