Key Characteristics
- Time Orientation: It looks backward at history, analyzing outcomes or exposures that have already occurred rather than tracking events forward in real time.
- Data Sources: It relies on existing records such as database logs, medical charts, insurance claims, or project documentation rather than creating new experiments.
- Hindsight Bias: Knowing the outcome in advance can skew how past decisions are interpreted.
- Data Gaps: Because the data was originally recorded for other purposes, historical records may be incomplete, inconsistent, or lack specific variables.
