panelkutatások
Panelkutatások, also known as panel surveys, are a research methodology that involves repeatedly collecting data from the same sample of individuals or households over time. This sample, referred to as a panel, is selected at the beginning of the study and remains consistent throughout its duration. The primary advantage of panel research is its ability to track changes and developments within the surveyed population. By observing the same units over multiple time points, researchers can identify trends, measure the impact of events or interventions, and understand causal relationships that might not be apparent in cross-sectional studies.
Panel studies can vary in length, from short-term projects lasting a few months to long-term longitudinal studies
