Not QGIS 4 ready Quiet
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Calculates sample size based on feature population, inspection level, and acceptable quality limit (AQL). Based on ISO 2859-2 and NBR 5425–5427.
About
This plugin calculates the sample size (n) from the population size (N) of a vector layer (feature class), based on the inspection level (I, II or III) and the acceptable quality limit (AQL). The population size (N) corresponds to the total number of features in the layer. The inspection level indicates the severity of inspection. The AQL defines the maximum proportion of nonconforming features allowed. The method follows ISO 2859-2 and Brazilian standards NBR 5425, 5426, and 5427. Este plugin calcula o tamanho da amostra (n) a partir do tamanho da população (N) de uma camada vetorial, com base no nível de inspeção e no Limite de Qualidade Aceitável (AQL). A metodologia segue as normas ISO 2859-2 e NBRs 5425, 5426 e 5427.
