* Translation: Data bias refers to systematic errors existing in data samples or the collection process, leading to the data’s inability to accurately represent the population it aims to study. This bias may originate from various factors like sampling methods, data sources, or the data processing process. Understanding data bias is crucial for avoiding incorrect conclusions and making informed decisions.

**Option 3: Emphasizing the consequences (Highlights the impact)**
