Quantitative Research Methods

Week Overview

Week 3 provides a deep dive into quantitative research methods — the systematic, numerical approaches used to measure variables, test hypotheses, and establish causal relationships. From experimental and quasi-experimental designs to cross-sectional surveys and correlational studies, you will learn how each design controls for threats to validity. This week also covers sampling strategies, statistical concepts, and how to interpret quantitative findings in the context of healthcare decision-making.

Learning Objectives

• Differentiate between experimental, quasi-experimental, and non-experimental designs
• Evaluate internal and external validity threats in quantitative studies
• Select appropriate sampling strategies for different research questions
• Interpret basic descriptive and inferential statistical results
• Assess the clinical significance of quantitative research findings
