Longitudinal Data Definition
Longitudinal data is a type of observational data collected from the same subjects repeatedly over a period of time.
Understanding the Options
Let's analyze the options based on the definition of longitudinal data:
- Option 1: Throughout the year - This describes the frequency or duration but doesn't specify if the same subjects are measured.
- Option 2: From same sample at different points of time - This accurately defines longitudinal data, emphasizing the repeated measurement of the identical group.
- Option 3: From same area but from different samples - This describes cross-sectional data collection across different groups, possibly in the same location.
- Option 4: For a long period of time at a stretch - This focuses on the duration but lacks the crucial element of repeated measurements on the same sample.
Conclusion
Therefore, the definition that correctly describes longitudinal data is collecting information from the same sample across different points in time.
