There are several reasons why comparing new findings with existing evidence is essential:
1. Validation: Ensuring that new results are consistent with previous studies strengthens the validity of the findings. 2. Contextualization: Comparing data helps place new findings within the broader context of existing knowledge, highlighting their significance or identifying anomalies. 3. Guidance: Existing evidence can inform the design, methodology, and interpretation of new studies, improving their quality and relevance.
