10.9 : Primary Data Collection Methods II

Quantitative research is essential for obtaining structured, numerical data that can be systematically analyzed to inform decision-making. This approach is widely used across various fields, utilizing surveys, panel data, scanner-based research, and experiments to gather actionable insights.

Surveys, often conducted online or in person, collect standardized data from large groups. For example, healthcare organizations might use surveys to assess patient satisfaction, guiding improvements in care delivery. Panel research tracks the same individuals over time to observe trends. A technology company, for instance, might use panel studies to monitor user experiences with a new software update, helping refine future developments.

Scanner-based research captures purchase data using barcodes or Radio Frequency Identification (RFID) provides real-time insights into consumer behavior. For example, grocery stores can use RFID to track products on shelves, manage inventory, and restock items quickly when they run low. Experimental research involves manipulating variables in controlled settings with control groups and randomization, vital in public health. Researchers might evaluate the effectiveness of health interventions, like vaccination campaigns, using the data to improve disease prevention strategies. These methods enable precise, data-driven decision-making across various sectors.
