Describing something as progressing "longitudinally" means it's measured or studied over a long period. This is often used in research, where data is collected from the same subjects repeatedly over time. Think of tracking the growth of a tree π³ over several years. Unlike a snapshot in time, a longitudinal study captures changes and trends. Medical research often uses longitudinal studies to see how diseases develop. Itβs a deep dive into how things change over time.
