Power BI developers design and refine data models to ensure statistical accuracy in reports. They structure data relationships effectively using star or snowflake schemas, reducing redundancy and ensuring consistency. Power BI developers validate datasets by performing checks for missing or inconsistent data, applying normalization techniques, and integrating statistical validation methods. They also implement DAX functions to create calculated columns and measures that provide accurate statistical insights. By focusing on data integrity and model efficiency, developers enhance the reliability of visualizations and analyses.
