Eight case studies from different crops and countries are used to demonstrate that sampling at different distances from possible sources of short-distance drift in most cases allows differentiating deliberate pesticide application by the organic farmer from drift. Datasets from 67 banana farms in Ecuador...
To draw valid conclusions from your results, you have to carefully decide how you will select a sample that is representative of the group as a whole. This is called asampling method. There are two primary types of sampling methods that you can use in your research: Probability samplinginvolv...

For thestratified sampling method, the sample is not completely random w.r.t. certain independent variables of the travel choice model (e.g. high income and low income). The sampling process is defined by functionf(X)f(X), giving the probability of finding an observation with characteristics...

Abstract Due to stigma or legal issues, populations with higher HIV risk are often hard to reach, which impedes accurate population estimation of HIV burden. To better sample hard-to-reach populations (HTRPs) for HIV surveillance, various sampling methods have been designed and/or used since HIV...
A total of 79 sampled studies (68.3% [95% CI, 59.3%-77.3%]) among the 1082 NIS studies screened for eligibility did not account for the effects of sampling error, clustering, and stratification; 62 (54.4% [95% CI, 44.7%-64.0%]) extrapolated nonspecific secondary diagnoses to infer in-...
