Can you explain how meta-analysis improves the reliability of research findings?

Certainly! By aggregating data from various studies, meta-analysis reduces the impact of individual study biases and increases statistical power.

What are some common challenges faced in conducting a meta-analysis?

Common challenges include heterogeneity among studies, publication bias, and the difficulty in obtaining raw data from original studies.
