Capture-recapture methods are statistical techniques used to estimate the size of a population by capturing a sample, marking them, and then recapturing another sample to see how many marked individuals are in that second sample. This method is commonly used in ecology to study animal populations but can also be applied in various fields such as epidemiology and social science to estimate unknown quantities. By analyzing the proportion of marked individuals in the second sample, researchers can derive estimates about the total population size.
congrats on reading the definition of capture-recapture methods. now let's actually learn it.
