How Precise is Precise Enough?

from Wildlife By The Numbers · host U.S. Fish and Wildlife Service

Grant, Matt, and Randy gear up to discuss precision, accuracy, and variability in wildlife studies. They dive into how variability measures data spread, using range, quartiles, standard deviation, variance, and coefficient of variation (CV).Accuracy reflects closeness to the true value, precision shows clustering of estimates. Standard errors, confidence intervals, and Bayesian credibility intervals quantify estimate precision. Required precision depends on study goals, sample size, and application, ensuring reliable, interpretable, and actionable results for wildlife management and conservation.They wrap up with some examples, but the take home message is deciding how precise results need to be hinges on the question and resources.Cite this episode: https://doi.org/10.7944/usfws.wbtn.s01ep011DOI Citation Formatter: https://citation.doi.org/ Episode music: Shapeshifter by Mr Smith is licensed under an Attribution 4.0 International License. https://creativecommons.org/licenses/by/4.0/https://freemusicarchive.org/music/mr-smith/studio-city/shapeshifter/
