variability in data sources

What are the common sources of variability?

Some common sources of variability in epidemiological data include:
Measurement Error: Variability can arise from inaccuracies in data collection instruments or methods.
Missing Data: Incomplete records can lead to biases if the missing data are not randomly distributed.
Data Integration: Combining data from different sources can introduce variability if the sources are not comparable.
Population Heterogeneity: Differences in demographic, socioeconomic, and health-related characteristics can affect data comparability.
