• "to ensure that research findings are accurate and true": The scientific method (hypothesis testing, replication, etc.) is designed to validate findings and minimize errors, ensuring accuracy.
• "to reduce the chances that personal opinions affect test results": The scientific method uses objective procedures (like controlled experiments, blinded studies) to reduce bias from personal opinions.
