Quantitative and Qualitative - What's the difference?
Summary
TLDRThe video script distinguishes between quantitative and qualitative research studies, highlighting their distinct data collection methods. Quantitative studies rely on numerical data like measurements and statistics to identify patterns, such as physical stress indicators. Qualitative studies, in contrast, use open-ended questions and interviews to delve into experiences and attitudes, uncovering underlying causes like a noisy work environment contributing to stress. Mixed methods studies combine both approaches for a comprehensive understanding. The script encourages viewers to identify the type of data collection in research studies they encounter.
