Because all measurement is fallible, the post-positivist emphasizes the importance of multiple measures and observations, each of which may possess different types of error, and the need to use triangulation across these multiple errorful sources to try to get a better bead on what’s happening in reality. Validity is the main extent to which a concept, conclusion or measurement is well-founded and likely corresponds accurately to the real world. Scribd is the world's largest social reading and publishing site. Rate, Ratio, Proportion, Measures of mortality, Measures of morbidity The beginning of population dynamics is widely regarded as the work of Malthus, formulated as the Malthusian growth model. Active surveillance requires substantially more time and resources and is therefore less commonly used in emergencies. Therefore, the proportion figures are multiplied by an appropriate number such as 10,000. Sensitivity analysis works on the simple principle: Change the model and observe the behavior.
