How can I minimize observer bias in my research?
You can use several tactics to minimize observer bias.
- Use masking (blinding) to hide the purpose of your study from all observers.
- Triangulate your data with different data collection methods or sources.
- Use multiple observers and ensure interrater reliability.
- Train your observers to make sure data is consistently recorded between them.
- Standardize your observation procedures to make sure they are structured and clear.
