These events often involve the counting of specific entities, such as cells, disease cases, or genetic mutations. In the context of biomedical research, count data can be thought of as the number of times an event of interest occurs within a defined sample or population.<\/p>\n<p>Count data is extensively used in various areas of biomedical research.
